/* ATLAS · components/legal-doc.css
 * Legal & Trust document anatomy (S073).
 * Design decision DD-LEGAL-1 (Wave 0): C + D hybrid —
 *   docs-style chapter flow (big § numerals + flowing sections) WITH a
 *   clause↔plain-language split column for the liability/disclaimer clauses.
 * Sticky left TOC rail (docs pattern). Atlas tokens only.
 *
 * Mandates honoured:
 *   M-1  no left-border-accent boxes — severity/notice encoded via mono eyebrow
 *        + pulsing index dot + FULL hairline frame. Round all four corners.
 *   M-3  premium finish — engraved rules, mono catalog stamps, optical spacing.
 *   M-4  disciplined motion — sections rise+fade on reveal (legal-doc.js),
 *        reduced-motion snaps to end-state.
 *   M-5  every font-size tokenized calc(px*var(--type-scale)); mono floor 11px.
