/* ==========================================================================
   Xaflo theme — base, chrome and xf- components
   --------------------------------------------------------------------------
   Colour has a job: Wire = structure/links, Ember = commands in motion,
   Mint = written and logged. Paper pills are the only primary button.
   Hairlines instead of shadows. One animated moment per page (the hero).

   NAMING: every component is xf-*. Old pages still inline their own CSS with
   xf-btn, xf-card, xf-sec, xf-faq, xf-stat, xf-tag, xf-code, xf-grid, xf-wrap,
   xf-hero, xf-prompt, xf-tbl, xf-copy, xf-mini, xf-app*, xf-chat, xf-msg ...
   Never reuse those exact names until those pages are rebuilt.
   Element base styles are scoped to .xf-migrated so legacy pages keep theirs.
