/* =====================================================================
   PinBoostr — Free tool pages.
   Loaded only on /free-tools/* (see pinboostr_is_free_tool_path()). Every
   class is prefixed .pb-ft-, which keeps it clear of retro-brand.css's
   !important recolours and of the Tailwind purge.

   Direction: an editorial reference card, not a landing page. One warm paper
   surface top to bottom — no hero band, no glow, no gradient text, no badges.
   Structure comes from hairline rules, numbered small-caps labels and a real
   serif/sans pairing. The tool sits at the very top and is usable straight
   away: the page IS the tool, not a pitch for it.

   Accent is one flat colour per platform, used only on the submit button,
   focus rings, links and the score numerals. Swap --ac, nothing else changes.
