/* ============================================================================
   THRESHOLD — public.css
   The public, unauthenticated surface: homepage, contact, emergency contacts,
   terms, privacy, data deletion.

   Load order: base.css -> tiers.css -> public.css

   WHY A SEPARATE STYLESHEET
   The app surfaces are a *tool* — dense, tier-driven, built for someone who may
   be impaired. These pages are *documents*, read by someone calm: a family
   member deciding whether to trust this, or an evaluator reading the policies.
   Different job, different rhythm. They share the tokens so they never feel
   like a different product, but they do not share the app's chrome.

   Everything here authors against the tokens in base.css. No new colours, no
   new type scale, no hardcoded hex values.
