fix(search): keep the phone results toolbar inside the screen

The search summary ("SW196AR · within 1 mile  Edit") ran about 40px off
the right edge on every phone, cutting "Edit" in half, and the filter row
bled past the screen with it (reported on an iPhone 17, 402px).

The phone toolbar is a column flex container, but it kept flex-wrap:
wrap from the desktop rule. In a wrapping flex container each line is as
wide as its widest item's content, not the container, so the summary's
~410px of text stretched the line past a 370px toolbar. nowrap makes
stretch mean the container's width. Verified on staging by injecting the
rule: nothing in the toolbar passes the right edge at 360 or 402px.

The E2E overflow check could not see this: .main clips on x, so
scrollWidth stayed equal to the viewport. The phone journey now measures
the toolbar's own right edges, and runs at 402px as well. It also waits
for the bottom sheet's slide-up to finish before measuring, and measures
the Map/List button again after the sheet pushes it up; both assertions
read a mid-animation or stale box before.

+# Other Schools Nearby — Design
+
+**Date:** 2026-09-21, revised 2026-09-22
+**Status:** revised after staging review
+**Scope:** school detail pages, both phase templates
+
+> **Revision, 2026-09-22.** The first build ranked by intake similarity and used
+> distance as a tiebreak. On staging a Catholic primary showed six Catholic
+> primaries, none of them close enough to be a real option, and omitted the
+> community school down the road. Distance now decides the order and nothing
+> else does; the tier system is gone. The reasoning is kept below rather than
+> quietly overwritten, because the mistake is the instructive part.
+
+## Goal
+
+Give a school detail page an answer to the question every reader arrives with
+after the results tables: *and what else is around here?*
+
+Today a school page links outward to its place pages through
+`components/school/NearbyPlaces.tsx` and nowhere else. It never links to another
+school. This section adds that edge — up to six nearby schools of the same phase
+and a comparable intake, three at a time in a carousel, each a crawlable link and
+each addable to the comparison basket in one click.
+
+Mockup, in both themes (drawn against the original tiered design, so its ledes
+and chip fallbacks are one revision behind the copy specified below):
+<https://claude.ai/artifact/168KdUMcfkUeGWW2FGjuec>
+
+Source of the same page in the repo: `mockups/similar-schools-nearby.html`.
+
+## The constraint that shapes everything
+
+**A nearby school is not automatically a comparable school.**
+
+The section's whole value is that a reader treats what it shows as a shortlist.
+That makes every card an implicit claim that the school is a realistic
+alternative, and there are three ways that claim goes wrong:
+
+1. A **selective** school beside a non-selective one. Their intakes are
+   different by construction, so putting their Attainment 8 figures side by side
+   invites a conclusion the data cannot support.
+2. A **special school, PRU or AP** beside a mainstream school. This is the same
+   error PR #70 fixed for the England benchmark, where Greenmead (URN 101099)
+   rendered "0% — 62 below England".
+3. A **single-sex** school of the opposite sex. Not a weak match — not an option
+   at all.
+
+So the design separates two kinds of fact, and never confuses them:
+
+- **Hard filters** encode the claims above. They decide eligibility, and are
+  never relaxed at any distance, even if that means the section does not render.
+- **Shared characteristics** — gender, religious character, selectivity —
+  describe how closely an intake resembles this school's. They are *reported on
+  the card and never ranked on*, so the reader weighs them rather than having
+  them weighed for them.
+
+Everything below follows from that split. The revision at the top of this
+document is what happens when the second kind is treated as the first.
+
+## Selection algorithm
+
+A backend helper, `_nearby_schools_payload(urn)` in `backend/app.py`, modelled
+on the existing `_places_payload(urn)` and delegating to
+`backend/nearby_schools.select_nearby(frame, urn)`, which operates on the cached
+`load_latest_school_data()` frame — one row per URN, already carrying
+`latitude`, `longitude`, `phase`, `gender`, `religious_denomination`,
+`admissions_policy`, `school_type` and `status`.
+
+### Hard filters
+
+| Filter | Rule |
+|---|---|
+| Self | `urn` is excluded |
+| Status | GIAS status must be open |
+| Coordinates | both `latitude` and `longitude` present on both schools |
+| Phase | same phase group via the existing `PHASE_GROUPS` map |
+| Provision | special/PRU/AP match only each other |
+| Selectivity | selective matches selective; non-selective matches non-selective |
+| Gender | Boys never matches Girls; Mixed is compatible with both |
+
+`PHASE_GROUPS` is reused rather than re-derived so an all-through school is
+offered correctly on both the primary and secondary sides, exactly as it already
+behaves in search.
+
+The provision filter needs a backend counterpart to the frontend's
+`isSpecialSchool()` in `nextjs-app/lib/utils.ts:897`, reading the same GIAS
+establishment types through `backend/gias_codes.py`. The two must agree: a
+school the frontend treats as special for benchmarking but the backend treats as
+mainstream for matching would be dropped from its own England comparison and
+then offered as a peer to a mainstream school on the next page along.
+
+**Up to six cards, three visible.** Three fit the row; the rest are reached with
+the carousel arrows. Two is the minimum that renders at all.
+
+### Order: distance, and nothing else
+
+The nearest eligible schools, closest first. Similarity does not enter the
+ranking at any point.
+
+**Why not, having built it the other way first.** The original design ranked by
+tiers — same gender and faith within 3 miles, then same gender within 5, then
+anything within 10 — and used distance only to order the result. Two things
+followed, and both showed up on the first Catholic primary anyone looked at:
+
+- A faith match at 2.9 miles outranked a community school at 0.3 miles. For a
+  primary, whose catchment is routinely under a mile, the far school is not a
+  weaker option; it is not an option.
+- Because the row filled from the best tier before widening, three Catholic
+  schools within 3 miles were enough to fill all six slots with Catholic
+  schools. The stopping rule that produced this had been added to prevent the
+  *opposite* failure — padding a row with weak distant matches — and made this
+  one certain.
+
+The premise was backwards. **Distance is a constraint and intake is a
+preference.** A parent cannot act on a school outside their reach however well
+it matches, and they are perfectly capable of noticing a shared denomination
+for themselves if we show it to them. So similarity moved from the ranking to
+the card: `shared` reports what a school genuinely has in common, and the reader
+applies their own weighting.
+
+The hard filters above were always where the defensibility lived. They are
+untouched.
+
+### Reach: a sanity bound, not a target
+
+| Phase | Reach |
+|---|---|
+| Primary, middle deemed primary, all-through | 2 miles |
+| Secondary, middle deemed secondary | 6 miles |
+| 16 plus | 10 miles |
+
+Ordering by distance already handles density — a school in inner London fills
+all six slots inside a mile and never approaches the cap. The cap decides one
+thing: what happens where the area is sparse. It differs by phase because
+catchments do, and because people travel furthest for post-16.
+
+**A primary with nothing inside two miles renders no section**, and that is the
+intended answer rather than a gap. The alternative is a section headed "nearby"
+listing a school four miles from a five-year-old.
+
+**Past the sixth school, the rest are dropped without a count.** The section
+does not try to be the list: `NearbyPlaces` sits directly beneath and already
+leads to the place pages, which are built for browsing a full set and which the
+school page exists to feed.
+
+**Fewer than two results renders nothing.** Not an empty state, not a single
+lonely card. The section is absent, the nav item is absent, and the page is
+unchanged from before it existed.
+
+### Distance
+
+Straight-line, from the vectorised haversine already used for postcode search at
+`backend/app.py:831`, computed over the ~27k-row frame in numpy. Reported to one
+decimal place in miles, consistent with the rest of the site.
+
+Straight-line distance is not road distance and is not measured from the
+reader's home. The section says so in its disclosure rather than leaving the
+reader to assume otherwise.
+
+## API
+
+`/api/schools/{urn}` gains a `similar_schools` array. Each row:
+
+| Field | Notes |
+|---|---|
+| `urn` | for the link and the compare basket |
+| `school_name` | link text |
+| `distance_miles` | one decimal place |
+| `school_type` | GIAS type, translated, for the card's meta line |
+| `age_range` | for the meta line |
+| `shared` | what this school genuinely shares with the subject; may be empty |
+| `metric_value` | the phase-appropriate headline figure, or null |
+| `metric_key` | `rwm_expected_pct` or `attainment_8_score` — see below |
+| `metric_year` | the year the figure is from |
+
+The metric follows the subject school's phase side, not the neighbour's own
+phase, so a row of cards never mixes two scales. The secondary
+side uses `attainment_8_score`; the primary side uses `rwm_expected_pct`. Where
+the neighbour has no value for that key, the card reads "Not published" rather
+than falling back to the other key.
+
+Which side a school takes is decided once, in
+`similar_schools.is_secondary_phase`, by membership of `PHASE_GROUPS["secondary"]`
+minus all-through — never by testing for the substring "secondary", which misses
+`16 plus` (GIAS phase 6) and hands a sixth-form college the primary bucket.
+All-through is the exception in the other direction: `PHASE_GROUPS` lists it on
+both sides, but it takes the primary metric.
+
+This is usually the same thing as "the template the page renders", but not
+always. `computeSchoolFlags` decides the template with that same substring test,
+so a `16 plus` school renders `PrimarySchoolSections` while being matched — 
+correctly — against secondaries. The section therefore takes its lede noun from
+the school's own phase rather than from its template, or it would print "Other
+primary schools near <sixth form college>" above a row of secondaries.
+
+Up to six rows of roughly 130 bytes each. It rides in the existing detail payload
+rather than a new endpoint because the page already makes exactly one server
+fetch for its data, and `/school/[slug]` regenerates at most weekly
+(`revalidate = 604800`), so the per-request cost is paid once per school per
+week.
+
+**The key is absent, not null, on a backend that does not have this code.** The
+frontend treats absent and empty identically, which is what allowed
+`NearbyPlaces` to ship without a lockstep deploy of the two images.
+
+`shared` is computed on the backend, beside the data it is derived from, not
+re-derived on the frontend. Deriving it twice is how a card comes to claim
+something the selection never established. An empty list is a real answer and
+renders no chips: a bare card costs a school nothing but the likeness it does
+not have, since the order was already settled by distance.
+
+## Frontend
+
+### Components
+
+`components/school/SimilarSchoolsSection.tsx` — a server component wrapped in
+the shared `Section` shell from `sectionShared.tsx`. It renders the heading,
+the lede, the card grid, the footer CTA and one caption line. Every
+card's title is an `<a>` to the school's canonical slug URL via `schoolUrl()`.
+
+`components/school/AddToCompareButton.tsx` — calls `addSchool` from
+`ComparisonProvider` and reports the selection with a `from: 'similar_schools'`
+attribution, mirroring `addSchoolFromSearch` in `HomeView.tsx:442`.
+
+`components/school/SimilarSchoolsCarousel.tsx` — the scroller and its arrows. It
+takes the server-rendered cards as `children` and the server-rendered heading and
+lede as a `header` prop, so those stay server components while the client
+component owns only the ref, the scroll handler and the arrows' disabled state.
+
+The split matters: the links — the part with SEO value and the part that must
+work without JavaScript — are server-rendered into the initial HTML, and only
+the basket interaction and the arrows are hydrated.
+
+### The carousel
+
+**Every card is in the initial HTML.** The arrows scroll a list; they never swap
+a view. Six `<a>` elements are in the markup whether or not anything is
+hydrated, which is the whole reason the section exists — a paginated widget that
+mounts cards on click would put four of the six links beyond a crawler and
+beyond a reader with no JavaScript.
+
+So the scroller is a plain overflowing `<ul>` with `scroll-snap-type: x
+mandatory`, and the arrows call `scrollBy` on it. With no JavaScript it
+degrades to a horizontally scrollable row that still works by touch and by
+trackpad. Three cards are visible at desktop width and two below 820px.
+
+**Arrows appear only when there is somewhere to go** — that is, only when more
+than three schools were found. Each disables itself at its own end of the
+travel.
+
+#### Below 640px the arrows go away
+
+This follows [MOBILE.md](../../../MOBILE.md), which makes 360px the design
+floor and mobile the primary target at ≥55% of traffic.
+
+Kept in the heading's flex row at 360px, the two arrow buttons take 96px from a
+328px card and crush the lede into a four-line column — measured, not guessed.
+And swiping already does what they do. So below 640px the header becomes a
+single column, the arrows are not rendered, one card shows at 86% width so the
+next one peeks, and the affordance is carried by the right-edge scroll-fade that
+MOBILE.md documents for exactly this case:
+
+```css
+mask-image: linear-gradient(to right, #000 calc(100% - 28px), transparent);
+```
+
+The fade lifts at the end of the travel, where there is nothing left to hint
+at. That means the at-end state must be computed whether or not an arrow exists
+to consume it — on mobile it drives the mask alone.
+
+**Every interactive element clears 44×44px**, per MOBILE.md's iOS HIG check: the
+arrow buttons and the add-to-compare button are both 44px, up from the 40px they
+were first drawn at. A card title's own box is shorter than that, but its hit
+area is the whole card through the `::after` overlay, so it passes on the target
+that actually receives the tap.
+
+**The edge test needs a tolerance, and this is not fussiness.** The scroller
+carries 2px of padding so focus rings are not clipped, and scroll-snap treats
+that padding as the first card's snap position: a scroller sitting at its start
+reports `scrollLeft` of 2, not 0. Sub-pixel rounding moves it again at other
+zoom levels. Testing `scrollLeft === 0` therefore leaves the back arrow live and
+pointing nowhere on first paint — confirmed in the mockup before it was fixed.
+Both ends compare against an 8px tolerance.
+
+**Selecting a school must not move the row.** Adding to the basket re-renders
+the footer; the scroll offset lives in the DOM rather than in React state, so
+the carousel must not remount or reset on that render. A reader who ticks the
+fifth school and is thrown back to the first has been punished for using the
+feature.
+
+### Placement and navigation
+
+Rendered as the last section **inside** `SchoolDetailShell`, from both
+`PrimarySchoolSections` and `SecondarySchoolSections`. Inside, not after, because
+the sticky nav's scroll-spy locates sections with `document.getElementById` and
+can only reach a section that lives in the shell.
+
+`NearbyPlaces` stays where it is, outside the shell, immediately below. The
+resulting order — this school, then similar schools, then the places containing
+them — narrows before it widens, which is the order a reader leaves a page in.
+
+`buildNavItems` and `buildSecondaryNavItems` both gain
+`{ id: 'similar', label: 'Similar schools' }`, gated on the section rendering.
+The id must match the `Section` id or the scroll-spy silently breaks.
+
+### The comparison CTA
+
+A plain `<a href="/compare?urns=…">`, built from this school's URN plus the
+selected ones. `/compare` already parses `urns` from the query string
+(`app/(frontend)/compare/page.tsx:55`), so this needs no new compare plumbing.
+With nothing selected the CTA is disabled; the button also adds to the shared
+basket so the site-wide comparison state stays consistent with what the page
+shows.
+
+## Copy, and what the section is allowed to claim
+
+**The lede never claims an intake.** It reads "Other primary schools near X." —
+one sentence, no variants. The earlier version varied the wording by tier, which
+only existed to soften a claim the section should not have been making.
+
+**The heading is "Other schools nearby", not "Similar schools nearby".** The
+hard filters do guarantee a comparable set — same phase, same selectivity,
+mainstream never beside special — but nothing ranks on likeness, so the heading
+does not say it does. The nav item reads "Nearby schools" and the section id is
+`nearby`.
+
+**Chips state only what is shared, and may be absent entirely.** A card with
+nothing in common renders no chip row rather than falling back to a filler.
+Since chips no longer affect the order, an empty one costs that school nothing
+except a claim it cannot support — and a Catholic parent scanning the row still
+spots "Roman Catholic" on the card that carries it, and weighs it themselves.
+
+**The neighbour's metric carries no valence colour.** Green and terracotta are
+reserved site-wide for comparison against the England average. Colouring a
+neighbour's figure against this school's would read as ranking the neighbours
+against each other, which is precisely the endorsement this section must not
+make. The figure sits in neutral ink above a plain "72% at this school"
+reference line, and the reader draws their own conclusion.
+
+**A missing figure reads "Not published".** Never 0, never blank, never an
+em dash. This follows the same rule the rest of the detail page uses: a school
+with no published result has not scored zero.
+
+**There is no "how these are chosen" disclosure.** The method is visible in what
+the section already shows — the phase in the lede, the shared characteristics on
+each card, the distance above each name — and a collapsed panel restating it
+earns less than the space it costs.
+
+**One caption line survives, and only one:** that distances are straight-line
+from the school and not road distance. This is not a method note. A reader who
+sees "0.6 miles away" and takes it for the walk has been misled by us, and no
+other element on the card corrects that. The remaining notes — that listing is
+not a recommendation, that special schools only meet special schools — are
+statements the selection rules already keep true without being narrated.
+
+## Degradation
+
+| Condition | Behaviour |
+|---|---|
+| `similar_schools` absent (older backend image) | no section, no nav item |
+| fewer than 2 qualifying schools | no section, no nav item |
+| this school has no coordinates | no section |
+| the helper raises | returns `[]`; the page renders without the section |
+
+The helper is wrapped so a failure inside it never 500s a page that is otherwise
+complete — the posture `get_supplementary_data` already takes for its own
+queries.
+
+## Testing
+
+**Backend**, in a new `backend/tests/test_similar_schools.py`, against a
+synthetic frame rather than live marts:
+
+- a selective school never returns a non-selective one, and vice versa
+- a special school returns only special schools; a mainstream school returns none
+- a Boys school never returns a Girls school; Mixed matches both
+- closed schools and schools without coordinates are never returned
+- results are ordered by distance ascending, always
+- a faith match never outranks a closer school (the staging defect, pinned)
+- the nearest eligible school is always present
+- more than six qualifying schools returns the six nearest
+- reach is capped per phase, and a primary beyond two miles returns `[]`
+- an all-through school is offered on both phase sides
+- a `16 plus` school is matched against secondaries and colleges, never primaries
+- `is_secondary_phase` and `PHASE_GROUPS` agree on every GIAS phase value
+- fewer than two qualifying schools returns `[]`
+- distances match a hand-computed haversine for a known pair
+
+**Frontend**, in `nextjs-app/__tests__`:
+
+- the section renders nothing for absent, empty and single-row inputs
+- the lede never claims a similar intake
+- an empty `shared` renders no chips rather than a filler
+- a null metric renders "Not published"
+- the nav item appears only alongside the section
+- every card is in the DOM, including the ones scrolled out of view
+- arrows render only when more than three schools were found
+
+jsdom has no layout, so `scrollWidth` and `clientWidth` are both 0 there and the
+arrows' disabled state cannot be meaningfully asserted in Jest. That behaviour is
+covered in the journey instead, against a real engine, rather than by a unit test
+that would pass on a measurement that does not exist.
+
+**E2E**, added to the existing journeys in `e2e/tests` in the same PR, per the
+repository's rule on user-facing behaviour:
+
+- the section renders on a known staging URN, with resolving links
+- where arrows are present, the back arrow starts disabled and the forward arrow
+  moves the row
+- selecting a school does not reset the scroll position
+- add-to-compare reaches `/compare` with the expected `urns`
+- at 360, 390 and 430px: no horizontal overflow, every interactive element in the
+  section clears 44×44px, and no arrows are rendered
+
+The E2E gate runs after merge on this project, so these journeys are not
+provable in the PR checks; the PR is verified on the unit tests, and the
+journeys are confirmed on the post-merge staging run.
+
+## Out of scope
+
+- A map of the nearby schools. The section is a list; the page already has a map.
+- Autoplay, dots, or an infinite loop on the carousel. It is a short list a
+  reader scans deliberately, not a banner competing for attention, and a row
+  that moves on its own is a row that moves while someone is reading it.
+- Statistical neighbours on deprivation, size or cohort profile. If plain
+  distance proves too blunt, that is the trigger to move this computation into a
+  dbt mart — `select_nearby` is a deliberate seam for exactly that swap.
+- Precomputing neighbours in `marts.*`. Rejected for now: a new mart is inert
+  until Airflow runs, so the feature would ship dark, and every tuning change to
+  the rules would become a pipeline round-trip instead of a deploy. The revision
+  at the top of this document is the argument for keeping that loop short.
+- Any change to `/api/compare`, the compare page, or the comparison basket.
