/*
 * Boardroom Design System v1 — implementation of
 * design/design-system/BOARDROOM_DESIGN_SYSTEM_V1.md Part 1 (Foundations).
 *
 * Scope note: only the tokens/components actually used by M6.5's four
 * foundational surfaces (login, application shell/home, CTO workspace,
 * account/consent) are implemented here — this is not a full component
 * library. Typography: Clash Display / Inter are referenced by name per the
 * design system doc; no font files were supplied with this milestone, so
 * both fall back to their nearest safe system equivalents until real font
 * assets are provided (a gap, not a silent substitution — see the
 * implementer's final report).
