/*
 * Fronset design tokens — the ONE source of colour, type, space and motion values.
 * Canonical copy: docs/brand/tokens/fronset-tokens.css (see docs/brand/DESIGN_GUIDELINES.md).
 *
 * Copies live next to each surface's stylesheet and must stay byte-identical to this file:
 *   sites/fronset/assets/css/fronset-tokens.css
 *   sites/llm-bench/assets/css/fronset-tokens.css
 *   apps/service_portal/static/service_portal/css/fronset-tokens.css
 *
 * Rules that the values below encode:
 *   - Dark is the default theme on every web surface. Light exists for e-mail, print,
 *     and anything that must sit on a white page. Opt in with class="fs-light" or
 *     data-theme="light" on a container.
 *   - Lime means "the pick" (the chosen model, the saving, the passing value). Nothing else.
 *   - Lime FILL may sit behind dark text on any theme. Lime TEXT or thin lime LINES are
 *     allowed on dark only — on light use --fs-accent-text, which becomes olive ink.
 *   - No @font-face in this file: font paths differ per surface. Each surface ships its
 *     own fonts.css (see DESIGN_GUIDELINES.md §5).
