/* ==========================================================================
   BOSTON STUDY HUB ACADEMY — brand + shell ("clean modern app" refresh)
   Loaded after every feature stylesheet (before print.css).
   · Brand: navy #0f172a (text only, used sparingly), red #e52e2e for fills /
     large accents, #c81e1e for small red text and the primary button (AA),
     gold #d4a83a (decorative: flame, race), star blue #2c4a9a ("On my own").
   · Light, airy surfaces: warm off-white page, pure-white cards, soft shadows,
     hairlines only where needed, 16–24 px padding, 600–700 headings.
   · Line icons: assets/js/icons.js (BC.icon) — 24 grid, 1.75 stroke.
   · Grouped, collapsible sidebar (BC.navConfig in app-core.js), calm Today
     page, Practice-hub tiles, mobile bottom tab bar (≤ 720 px).
   · Dark navy stays only on projector views (race projector, prep code) and
     print — those live in race.css / week.css / print.css, not here.
   Contrast: scratchpad contrast.js (all text pairs ≥ 4.5:1).
