/*
 * Customer Assets for JSM Portal — product website stylesheet
 * ------------------------------------------------------------------
 * One shared stylesheet for every page. No external requests: system
 * fonts only, no web fonts, no CDN, no images loaded from CSS.
 *
 * Contents
 *   1. Design tokens (light + dark via prefers-color-scheme)
 *   2. Base / reset
 *   3. Accessibility helpers (skip link, focus, reduced motion)
 *   4. Layout primitives
 *   5. Header + navigation
 *   6. Buttons, links, placeholders
 *   7. Hero
 *   8. Sections, cards, feature grids
 *   9. Diagram, steps, gallery
 *  10. Tables, FAQ, callouts, tags
 *  11. CTA band + footer
 *  12. Utility
 *
 * Contrast notes (WCAG 2.2 AA): brand turquoise #30afc0 is only 2.4:1 on
 * white, so it is used for decoration and on dark backgrounds only. Text
 * and interactive colour on light backgrounds is brand violet #791496
 * (8.9:1 on white). In dark mode the interactive colour is a light
 * turquoise (#8fd6e1, > 8:1 on the dark background).
