/**
 * FounderOS design tokens — the single source of truth (#1786).
 *
 * Canonical home of the N1 token ramp for EVERY surface. Consumers:
 *   - apps/fos-bridge/fosBridge/tokens.css — GENERATED copy (scripts/sync-tokens.mjs),
 *     held in lockstep by __tests__/tokens-lockstep-1786.test.mjs. Never hand-edit.
 *   - apps/cloud-ui/src/styles/tokens.css — still the local original; repointing
 *     cloud-ui here and deleting that copy is the #1786 follow-up PR.
 * Change tokens HERE, run the bridge sync, and both surfaces move together.
 *
 * Component CSS consumes these and MUST NOT redeclare the :root token block —
 * that fork is what N1 removed.
 *
 * Two orthogonal axes on <html>:
 *   [data-theme]   = dark (default) | light
 *   [data-surface] = foundry (alpha, default) | bridge (beta customers)
 * data-surface overrides accent + brand chrome only; the structural ramp
 * (bg / text / line / spacing) is shared so one layout themes twice.
