/* ==== base:begin ==========================================================
 * 02AI Workbench design system: tokens, reset and shared primitives.
 *
 * Canonical copy. This file is NOT served: every page stylesheet
 * (web/studio/style.css, web/admin/style.css, web/auth/style.css) starts with a
 * verbatim copy of everything between the base:begin and base:end markers, so
 * each page stays one same-origin stylesheet (CSP style-src 'self', and the
 * sign-in page is served before the sign-in gate). tests/frontend-base.test.ts
 * fails when a copy drifts. Edit here, then paste into all three.
 *
 * Rules the browser code follows (tests/server.test.ts, admin-routes.test.ts):
 * no inline styles and no `.style.` from script. Dynamic visuals use classes,
 * SVG attributes, <progress>/<meter> or data-* attributes.
