/* The Board — showcase site.
   Brand source: design_handoff_design_system/ds/tokens + reference, and
   the shipped war-room GUI (ffdraft_gui/static/style.css) — the hero and
   tile treatments mirror the app's homepage.
   Note: glass surfaces here use tint only, no backdrop-filter — dozens of
   backdrop blurs over the fixed nebula black-frame Chromium's compositor,
   and blurring a smooth gradient is visually a no-op anyway. */
