/* ============================================================
   info.css — Phase 5 static / informational pages.

   Five surfaces share this file: /about, /faq, /termsofuse,
   /error, /guides, /rivers, /contact. Prose-heavy pages needed
   one new layout pattern (an authored-text column at a reading
   measure) but the rest — headings, buttons, banners — reuse
   the alerts + components vocabulary.

   Intentional constraints:
   - No new colors. Every value here is a token.css reference.
   - No new spacing. Token scale only.
   - Prose body size sits between alerts-form body (15px) and
     dense-data rows (13.5px). 16px is a reading-comfortable size
     without needing a dedicated type ramp.
