   MONOCHROME legal DOCUMENT (One's ruling): the legal document itself is
   black + white — emphasis is carried by size, weight, border and
   whitespace, never by hue. NO gold, NO orange.
   ★ SCOPE: monochrome applies to the DOCUMENT ONLY. The shared site
   chrome (header, FIQH logo, Beta badge, navigation, search, auth
   controls, footer and its red FIQH wordmark) keeps its normal Index
   branding — this file must never redefine shared/global brand
   variables, and must never repaint #header-placeholder /
   #footer-placeholder. The accent override below is therefore scoped to
   the legal-document containers, not to :root.
   Base tokens resolve via css/tokens.css. Fonts (Rule 24): Sarabun body ·
   IBM Plex Sans Thai headings · D-DIN labels · Amiri Arabic.
   Components: hero (.legal-*), comparison (.mt-compare),
   critical summary (.mt-summary), sticky-TOC layout (.legal-doc),
   restrained notice (.legal-callout), related docs (.legal-related),
   mobile สารบัญ (.legal-toc-mobile), print rules.

/* ── MONOCHROME accent — SCOPED TO THE LEGAL DOCUMENT ONLY ────────────
   Custom properties inherit, so redefining the accent on the document
   containers turns every legal component black without touching anything
   outside them. The shared header/footer live outside these containers
   and therefore keep the global brand red from tokens.css.
   ★ Never move these to :root — that is exactly what leaked the
   monochrome into shared site chrome. */
