/* ClaimAid v0.2 — design system.
   Wise-inspired: warm off-white, near-black ink, lime accent, pill CTAs,
   dark hero band. Zero external dependencies (CSP: no CDNs, no fonts,
   no analytics, no external images). All styling via classes.
   Backwards-compatible: every class used by app.js / checker.js /
   v0.1 pages is still styled. */
