/* SinEnergy website (decision 0005, restart). System fonts, no third-party request, logical properties only
   (RTL and LTR from one file). Palette A (Brand and Identity section 6): Paper (page), Navy (brand colour: bands,
   footer, page headers), SE Blue and Leaf as the only accents. Text-safe tones: #1a6fe0 and #35721a on paper,
   #4F9BFF and #5DB234 on navy.

   Themes: LIGHT BY DEFAULT, dark is a switch. Every colour token is one light-dark(light, dark) pair, so there is a
   single token block. color-scheme is "light" on the root; /assets/theme.js sets data-theme="dark" on <html> (the
   header switch, saved in localStorage) and the dark half applies. The OS preference does not decide.

   Fonts: the tokens --font-display, --font-text and --font-arabic hold system stacks today. Self-hosted web fonts are
   planned (owner, 2026-11-08), but no font file is added until the owner approves specific files. To add one:
   copy the .woff2 into src/assets/fonts/ and uncomment/adapt a rule such as

     @font-face { font-family: "SE Display"; src: url("/fonts/se-display.woff2") format("woff2");
                  font-weight: 600; font-display: swap; }

   then put "SE Display" first in the matching token below. Never a font service (no request to another site). */
