/*
 * ainventry landing v2 - design tokens. Copy this file to landing/tokens.css unchanged.
 * Spec and rationale: DESIGN_SYSTEM.md (same folder). Direction: "Ledger Paper".
 *
 * Two families:
 *   --inv-*  verbatim copies of frontend/design-tokens.css, so the page and the app share one language.
 *            Only the subset the landing reads. Never change a value here; change it in the app first.
 *   everything else  landing-only: accent scale, signal, the dark AI-band palette, the violet pricing band,
 *            fluid type, spacing, radii, shadows, motion.
 *
 * Components never read raw palette tokens. They read the semantic --c-* set, which a band class
 * (.band--night, .band--violet, .band--ink) re-points. Light paper is the default scope.
 * Every text/background pair used below was measured; ratios are in DESIGN_SYSTEM.md section 2.
 *
 * CSP: this file holds no url(), no @import, no data: URI.
