/* Mythos ERP — design system component layer.
 *
 * Built entirely on assets/tokens.css, which is a VERBATIM copy of the Hub's
 * token file. That is deliberate: the ERP and the Hub cannot drift if they
 * read the same values. If a token is missing here, add it to the shared file
 * rather than inventing a local one.
 *
 * Rules this file keeps, and the legacy stylesheets did not:
 *   - no literal colour values (the legacy CSS has 63 distinct hex values and
 *     399 rgba() calls across 3,244 lines)
 *   - no !important (the legacy CSS has 188)
 *   - no inline styles and no inline event handlers — the platform CSP is
 *     script-src 'self', which forbids both
 *   - one 35° gesture per view (A-012): the topbar rule, nowhere else
