   Most card/badge/pill classes (.kb-card, .tlr-priority, .pri-*,
   .tlr-avatar, .task-filter-pill, .board-head*) already live in
   design.css; this only adds the board chrome + column grid.

/* ───────────────────────────────────────────────────────────────
   Task Board — detail / add / archive MODAL
   ---------------------------------------------------------------
   Root cause of the unstyled "Task" popup (paste-1781025025267.png):
   the design migration links design.css but NOT board.css. design.css
   defines `.board-modal` as a *card* (board-modal-overlay + board-modal)
   while our markup uses `.board-modal` as the full-screen OVERLAY and
   `.board-modal-card` as the card — the board.css semantics, which have
   no styles loaded. design.css also lacks `.board-modal-card`,
   `.board-detail-*`, `.bd-comment-*`, and `.board-archive-*`, so the
   meta / comments / compose blocks render as plain text.

   Fix (CSS-only, same pattern as the Events sub-tab restore): port the
   board.css modal block here (overrides.css loads AFTER design.css). We
   explicitly RESET the width/border/radius/shadow/transform that
   design.css's `.board-modal` card rule would otherwise leak onto our
   overlay element. No JS / no API callsite touched.
