/* BuyDocs — shared theme
 * --------------------------------------------------------------
 *
 * Loaded by every page. Provides the base typography, the design
 * tokens that every page-level CSS already references via :root,
 * a unified pagination component, and a mobile responsive layer.
 *
 * Colors are tuned for warmth + clarity:
 *   - Gold is the brand accent; not the page background.
 *   - Whites are slightly off-white so light cards have a
 *     visible edge against the page.
 *   - Greys have proper contrast progression for hierarchy.
 *
 * Page-specific component CSS still lives inline in each
 * template; this file only defines tokens and a few shared
 * components, so changes here propagate visually without
 * touching templates.
