/* ============================================================================
   MODULE 14 — DESIGN TOKENS. THE SINGLE SOURCE OF TRUTH FOR HOW RUSS LOOKS.
   ============================================================================

   These are the WC RUSS tokens, carried across verbatim — names and hex values
   both — because the identity is proven and Module 14's brief is explicit that
   it must not be reinvented. Module 12 shipped a provisional palette with
   different names (`--bg`, `--surface`, `--accent`, `--gold`, `--pink`); every
   component was migrated to the names below in one pass, so the site now speaks
   ONE vocabulary rather than a canonical set plus an alias layer.

   ONE DELIBERATE DEVIATION, MEASURED — `--text-muted`
   --------------------------------------------------
   The brief asks for the palette verbatim AND for WCAG AA contrast. On this
   palette those two requirements conflict in exactly one place. Measured
   (relative luminance, WCAG 2.1):

       #7a86a8 on --bg-primary     5.32  ✓
       #7a86a8 on --bg-card        4.74  ✓
       #7a86a8 on --bg-card-hover  4.27  ✗   AA normal text needs 4.5

   That pairing is reachable, not theoretical: `.log tr:hover td` and
   `.table .row.clickable:hover` both swap the row to `--bg-card-hover`, and
   both carry muted text. So the token is lightened to the SMALLEST value that
   clears 4.5 on all three surfaces: hue 224.3° and saturation 0.209 are
   unchanged, HSL lightness moves 0.569 → 0.585. Every other token in this
   block is byte-for-byte the brief's.

       #7f8aab on --bg-primary     5.62  ✓
       #7f8aab on --bg-card        5.00  ✓
       #7f8aab on --bg-card-hover  4.51  ✓

   An accessibility floor outranks two hex digits of fidelity, and the check is
   executable rather than asserted: `tests/test_design_tokens.py` recomputes
   every foreground/background pair and fails if any drops below AA.

/* BACKLOG #104, second pass. `.table` used to carry `overflow: hidden` purely
   to clip the first/last row's square corners to the container's own
   border-radius. That declaration also makes `.table` the nearest ancestor
   with a "scrolling mechanism" for CSS purposes (MDN, position:sticky), and
   because `.table` never itself scrolls (no max-height — it grows to fit all
   rows, so scrollHeight === clientHeight always), the sticky header below
   could never engage: it just sat in normal flow, one row above the first
   data row, contributing nothing and clashing with nothing on its own. The
   corner-clip is moved onto the first/last row directly (border-radius
   respects an element's own background) so `.table` no longer blocks the
   sticky rule from resolving against the real scrolling ancestor — the page,
   same as `.tabs`. NOT visually confirmed — no browser here (#52, #66). */

/* BACKLOG #181. The twelve columns of the predicted table are fixed pixel
   tracks (app.js sets them inline as --table-cols) and sum to 460px; add
   11 x 8px gaps and 2 x 12px of row padding and the row cannot be narrower
   than 572px before the flexible team column has any width at all. The card's
   content box is only viewport - 58px here (main 2x12, card 2x16, borders
   2x1), so a 390px phone offers about 332px. #104 removed `.table`'s
   `overflow: hidden`, which had been silently clipping that excess off the
   right edge, so without the rule below the overflow now pushes the WHOLE
   PAGE sideways — worse than the clipping it replaced. The table scrolls
   inside its own box instead: the same idiom as `.fixture-table` and
   `.heat-wrap`. The floor on `.team-cell` overrides the `min-width: 0` above
   so the team column keeps room for the 22px crest, its 8px gap and a few
   ellipsised characters, rather than collapsing to nothing once the fixed
   tracks have taken everything.

   THE TRADEOFF, written down because #104 and check 40 exist precisely to
   stop it being introduced silently. A non-visible overflow on one axis makes
   the element a scroll container on BOTH — the CSS overflow rules forbid a
   visible/non-visible pair and promote the visible one — so below this
   breakpoint `.row.head`'s sticky positioning resolves against `.table`
   instead of the page, and `.table` has no max-height, so it never scrolls
   vertically and the header does not stick. That is exactly the #104 defect,
   deliberately re-accepted BELOW 720px ONLY. It is not a regression of #104:
   above the breakpoint the header still sticks, and below it the header row
   is ~668px wide against a ~330px viewport, so a header pinned to the top
   would show two of its twelve columns. Losing it there costs almost nothing;
   a page-wide horizontal scrollbar costs a lot. No pure-CSS arrangement keeps
   both — a horizontally scrolling ancestor IS a scroll container. The only
   alternative that keeps the header sticky is giving `.table` a max-height so
   it scrolls vertically too (the `.board-wrap`/`.log-wrap` idiom), which
   turns the table into a nested scroll pane on a phone; that was judged worse
   and is recorded in #181 rather than silently discarded.
