/*
 * Scholix base layer — styles for themes/base/* views.
 *
 * Base views render a page or section that the active theme does not provide
 * itself (instead of borrowing another theme's markup). They must look
 * acceptable inside ANY theme, so this file:
 *   - uses only the platform tokens every theme emits (shared/design-tokens):
 *     --primary-color, --text-color, --border-color, --cta-*, fonts, …
 *   - prefixes every class with "sx-" and depends on no CSS framework or icon font
 *   - wraps selectors in :where() (zero specificity) so a theme's own element
 *     styles (headings, links, buttons) still apply and can restyle base output.
