   Red Mammoth — shared site stylesheet
   Loaded by every standalone page (index.html + all converted pages).
   Contains: design tokens, base reset, header, footer, buttons, and the
   handful of section/card patterns that are byte-for-byte identical across
   two or more pages. Anything that varies between pages — even by a single
   pixel — stays out of this file and lives in that page's own CSS instead,
   so nothing here silently changes another page's look.
