/* FPL-001/REQ-002 (codeperts #3186) — the one token file. 332 declarations (315 + --crumb-max-w, --drop-line, the two time-picker tokens of item 39, --series-5…--series-9 of item 42 and the five Grid tokens of item 45 and --busy-area-delay of FPL-001/REQ-039, row 87 and the two content-cell tokens --heat-content-w / --heat-content-h of FPL-001/REQ-038, row 30 — see claude-docs/UI-LAYER.md §2), one :root rule.
   Source: the finalized sheet's eight :root blocks (../mockups/01-shell.html … 08-page-parts.html),
   flattened per FR-2's four rulings (--search-w-bar dropped, --tip-lane-h/--menu-lane-h dropped,
   --drawer-w-list/--scrim-navy aliased). The sheet is FINAL (DEC-011) — a disagreement between this
   file and the sheet is a defect here, never the other way round.
   No other selector may exist in this file (FR-4, ELEMENT_RULE_IN_TOKEN_FILE) and no other layer
   file may redeclare a name from this set (TOKEN_REDEFINED_OUTSIDE_LAYER). See claude-docs/UI-LAYER.md. */
