   SIPI v10 — Design Tokens
   Source of truth: docs/v2-source-of-truth/sipi_v10_mock.html (Task A2)
   Updated 2026-04-29 to align with the SIPI Extended Colour Palette v2
   (sipi_extended_colour_palette_v2.html). Two new foundation colors
   added (teal-pale, navy-deep) + a parallel --sipi-* alias namespace
   so future CSS can use the v2 vocabulary without breaking the
   existing ~150 references to the short names.

   Both naming conventions resolve to the same value:
     --teal-dark      ===  --sipi-teal-dark   (#085041)
     --navy           ===  --sipi-navy        (#051C2C)
     ...etc

  /* --gold-text: WCAG-AA compliant variant of --gold for text-on-light
   * contexts. The brand gold (#B8973E) measures only 2.78 contrast on
   * white — fails the 4.5 threshold for normal text and 3.0 for large
   * text. This darker shade keeps the same hue but lifts contrast to
   * ~4.7 on white and ~4.4 on --off (#F5F5F3). Used by `.lbl` and `em`
   * by default in base.css; the original --gold is restored on dark
   * surfaces (.ph header, .tao-overlay, .flip-back, .foot, .dark, etc.)
   * via explicit overrides because gold-on-navy already passes AA. */
