/* ResumeRadar — guides.css
 * ---------------------------------------------------------------------------
 * Article / prose + SEO Guides-hub styling for the /guides/ section.
 *
 * Built ENTIRELY on the design tokens defined in styles.css :root (the --rr-*
 * custom properties, the fluid type scale --fs-*, the spacing scale --sp-*,
 * radii, shadows, motion easings). NOTHING here hardcodes a hex value — every
 * color comes from a token, so the light-preference override and any pro.js
 * runtime --rr-accent swap keep working on guide pages too.
 *
 * This file is ADDITIVE. styles.css must be loaded FIRST (it provides .topbar,
 * .brand, .btn, .sitefooter, the reset, tokens, reduced-motion kill-switch,
 * the global :focus-visible ring, etc.). We only add guide-specific rules and
 * reuse existing classes wherever it makes sense.
 *
 * Accessibility baked in: 44px minimum tap targets, focus-visible rings that
 * inherit the global outline, WCAG-AA contrast on the dark navy theme (body
 * copy uses --rr-text on --rr-bg; muted copy stays >=4.5:1), and a full
 * prefers-reduced-motion path (the styles.css kill-switch already neutralizes
 * transitions; we add nothing that fights it).
