The fade between the map band and the school header ramped through rgba(255,255,255,...) and landed on var(--bg-card). In the light theme that is white into white and invisible, as designed. In the dark theme it climbed to 95% WHITE and then met a near-black card, putting a bright band across the full width exactly where the map should dissolve into the title. Fading to the colour the gradient lands on is the whole trick, and it only works if that colour is a token — so --bg-card-rgb now exists in both theme blocks, matching the --hero-ground-rgb precedent. Two more defects in the same file, same cause, found while in there: The controls floating over the map paired a hardcoded white background with color: var(--text-primary), which resolves to #E9EEF0 in dark — near-white text on a near-white button. These deliberately do NOT follow the theme, because the map tiles are light in both, so the ink is now literal too and says why. A themed token is the wrong tool for a surface that never changes. The loading skeleton swept 50% white across var(--bg-secondary), which is a bright flash every 1.4s on a dark page. It now sweeps toward the card colour, a shade lighter than the ground in both themes. The guard is a stylesheet test rather than a render test, because the bug is invisible in the theme it was written for. Verified by reverting each fix in turn: it names .fade and .openHint exactly.
