/* =========================================================================
   Flyingfish Capital — public site stylesheet
   Sprint 04 / T3 scaffold. Shared styles + brand tokens.

   Brand palette source of truth:
     customisations/branding/flyingfish-capital/theme/_theme-colors.scss
     primary  #3E4A9E  (deep indigo-blue — brand mark)
     accent   #FEAB41  (warm amber — call-to-action / large figures)
     support  #4D83B2  (support blue — info panels / secondary)

   Accessibility note: amber (#FEAB41) on white has LOW contrast. It is
   reserved for LARGE/BOLD figures and the Calculate button surface only,
   NEVER for body text. Primary text/headers use indigo or near-black neutral.

   ZERO external network requests: no @import of remote fonts, no CDN.
   ========================================================================= */

/* ---- Self-hosted fonts ---------------------------------------------------
   No brand web-font (woff2) files exist in the repo yet, so the safe default
   is a system-font stack (zero network requests, fast, legible on low-end
   PNG field devices). When self-hosted woff2 files are dropped into
   web-public/fonts/, uncomment and complete the @font-face block below and
   add the family name to --ff-font-sans. See web-public/fonts/README.md.
