/*
  Trua I-9 design system — v2 (2026-06-04 design push).

  Structure top-to-bottom:
    1. Tokens — palette, type scale, spacing, radii, shadows
    2. Bootstrap overrides — re-map Bootstrap 5 vars to our tokens
    3. Component primitives — button matrix, breadcrumb, page header,
       badges, cards, tables, forms, alerts, dropdowns
    4. Surface tonal layers — .surface-employer, .surface-wallet,
       .surface-inspector pick their density / color emphasis
    5. Legacy class mappings — .tt-*, .i9-*, .w-*, .insp-* keep working
       and inherit the new tokens, so existing views look new without
       being touched. The view sweep migrates them to explicit classes
       over follow-up commits.

  Design language: architectural. Tight radii (right angles convey
  reliability and authority — see shape-psychology rationale in
  docs/style-guide.md). Strong grid presence. Crisp 1px borders, not
  soft shadows. Sentence case (no uppercase letter-spacing). Inter
  does all the typographic work — regular + semibold + bold only.

  /* --- Legacy aliases (preserve v2 token surface for unswept views) ---
     v2 used --navy-* / --light-* / --dark-* heavily across ~63 view
     references. Rather than touch every view in this commit, alias the
     v2 names to the v3 scales. Future view-sweep commits can migrate
     to explicit v3 names; nothing breaks in the meantime.

     Mapping rationale: navy-70 was the v2 "structural anchor heading"
     color (#1A365D) — closest v3 equivalent is blue-900 (#15264C, very
     close in hue + value). light-* → neutral-* shift their off-white-ish
     surfaces to the cleaner neutrals from the brief. dark-* fold into
     neutral-700/900 since the v3 brief consolidates dark gradations.

     The retired --orange-* scale is NOT aliased — any view that
     references --orange-* should now fail loudly, signaling a sweep
     is needed. (At commit time, only one such ref existed and was
     migrated; future regressions are easier to catch by absence.) */
