   TENET5 — brand-lock.css (Cap#258, 2026-04-27)
   PURPOSE: Brand tokens MUST win the cascade against inline_generated.css
   and any auto-cycle injection. Seed-anchored to SYSTEM_SEED=118400.
   Per memory:feedback_css_spec_seed_anchored_max_enforcement.md and
   memory:feedback_css_theme_must_be_unconditional_and_auto_applied.md.

   This file is loaded LAST in css/tenet5.css's @import chain so its
   declarations cascade after slate-tokens.css, liril-theme.css,
   inline_generated.css, and anything else.

   RULE: every brand-critical token MUST be !important here, and at
   plain :root (not :root[data-slate=*]). shell.js may set data-slate
   as defense-in-depth but the tokens themselves are unconditional.
