/* ==========================================================================
   Platform theming
   ==========================================================================
   Driven entirely by the "Platform Color Theme" field (module.platform_theme)
   which module.html renders as data-enm-theme="..." on the .enm-root wrapper
   that everything else lives inside. Every themed color in this file reads
   from the --sf-accent(-rgb) / --sf-hue2/3(-rgb) / --sf-hue4-rgb custom
   properties above rather than a literal color, so overriding those four
   properties here re-colors the accent text, buttons, borders, glows, the
   background aurora and the heading shimmer everywhere at once.

   Primary --sf-accent values are each platform's real brand color (sources:
   Brandfetch brand profiles + each platform's own live site, checked
   September 2026 — Bizzabo in particular has moved on from the blue some
   directories still list, to the yellow their current site actually uses).
   The --sf-hue2/3/4 values are NOT hand-picked per platform — they're the
   default teal/violet/indigo/emerald aurora hues uniformly hue-rotated by
   the same amount as the accent color, so every theme keeps the same
   internal color harmony as the original design instead of needing 40+
   individually chosen values. Treat --sf-accent as "verify against your
   brand kit if exact accuracy matters"; treat --sf-hue2/3/4 as ambient/
   decorative only. */
