/* Phase 1 — chrome.
   Re-skins the existing top bar, side rail, page-header, buttons, cards,
   chips, table, and outcome surfaces using v2 tokens. Targets BOTH the
   legacy class names rendered by today's templates (`.tc-topbar`,
   `.tc-sidebar`, `.outcome-pill`, …) AND the new `tc-c-*` component
   classes documented in `04_component_patterns.md`, so future templates
   can migrate one surface at a time. */
