/* Neuractor site v2 · Brand 3.0, option 03 "Gain" (Thu 8 Oct 2026). One stylesheet for / and /ar/.
   COLOUR: every colour on this site comes from the GENERATED block below, which _tools/apply_brand.py writes from a
     palette file (brand3/colour/PALETTE-SCHEMA.md). The hand-written rules after the block use role tokens only and
     contain no colour literal (verify.py fails on a hex, rgb() or named colour outside the block).
     The spark (the small square ahead of the five bands) is the recurring device: section labels, list markers and
     the highlighter behind "page 14". On light grounds it falls back to a stronger role when the palette's spark is
     below 3:1 there (apply_brand.py decides and prints why).
   TYPE: Instrument Sans (Latin, wght 400-700, wdth 75-100) and Alexandria (Arabic, wght 100-900), self-hosted
     woff2 subsets from brand-final/fonts/web (SIL OFL 1.1; assets/fonts/SOURCES.txt). Labels use Instrument Sans at
     87.5% width; references use its tabular figures.
   LAYOUT: logical properties only, so the same rules serve left-to-right and right-to-left. The mark itself is never
     mirrored: its output always faces right, and in Arabic it sits at the line end (left).
   No external requests: no CDNs, no Google Fonts. Western digits everywhere. */
