/*
 * linear.css — Linear-style, editorial-restrained treatment layer for fo-scraper-miwi.
 *
 * Loaded AFTER eyerest.css/fonts.css/layout.css so it wins the cascade. It does three things:
 *   1. Swaps the EyeRest gold palette for the Linear palette (dark-first) by redefining the same
 *      color tokens in the SAME selectors eyerest.css uses (later source order → override).
 *   2. Overrides layout tokens (shell/prose widths, radii) and adds a type + motion system.
 *   3. Provides the bespoke landing + dashboard components.
 * Rule: one accent (--primary) for CTA/focus/link only; one hero glow; nothing else glows.
 * Tokens are the design source of truth in docs/plans/003-mvp-landing-dashboard.md.
