/* TPS (Tomokore Persona System) — shared design system for the Phase 1 public site.
   Loaded by every page under /docs/tps/. Keep this the single source of visual
   truth; do not fork per-page copies of these tokens.

   Palette/typography deliberately mirror the Tomokore Web hub (index.html,
   docs/index.html): a bright, cheerful warm-cream-and-orange look (not a
   blue/aqua "ocean" palette) rather than the old deep-ocean-navy brand, plus
   the Hiragino/Yu Gothic + Yu Mincho font stacks already used elsewhere on
   this domain, so TPS reads as part of the same product rather than a
   separate "report" site. */
