The compare chart squashed clustered schools into a thin band (y pinned 0-100) under an in-chart title + per-school legend that ate ~40% of a 300px card, leaving converging lines indistinguishable on phones. - Auto-fit the y-axis to the data on all viewports (computeYBounds in lib/utils: padded + min-span for percentages, symmetric around 0 for progress, fitted for scores; negative pct-named trend metrics are not zero-clamped). - Distinct point style per school (circle/triangle/rect/rectRot/star) as secondary encoding for convergence and colour-blindness. - Mobile: drop in-chart title/legend/axis titles; add a chip row (colour dot + name) that doubles as tap-to-focus — highlights one school's line and dims the rest. Chart card 300px -> 340px, nearly all plot. - Fix a latent colour mismatch: datasets were built from Object.entries whose integer-like URN keys enumerate in ascending numeric order, desyncing line colours from card colours; the chart now receives the ordered school list. - Union years across schools instead of taking the first school's. - Extract PerformanceChart's matchMedia pattern into hooks/useIsMobile. Unit tests for metricKind/computeYBounds; e2e journey covers the mobile chips and focus toggle. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
