   WebShield Navy — locked palette system
   Status: LOCKED (project 1, palette exploration, 2026-04-20)
   Register: Institutional navy — law-firm / investment-bank
   All subsequent components in this project and the downstream full-page
   composition project must source color from these tokens.

   v1.3 (2026-04-21) — body font sizes bumped ~10% after live browser
   testing showed cramped text at desktop viewport. Affects --ws-fs-lede,
   --ws-fs-body, --ws-fs-body-sm, --ws-lh-body only. See CHANGELOG.md.
