/*
 * INFOSHOK — Base Stylesheet
 *
 * All colours and decorative values are drawn from CSS custom properties
 * set by the active theme file. This stylesheet is theme-agnostic: it
 * provides structure, rhythm, and component patterns. Swap the theme
 * and the whole shop changes face.
 *
 * Design principles:
 *   - Utilitarian. No decoration for decoration's sake.
 *   - Legible. System fonts, generous line-height, clear hierarchy.
 *   - Functional. Every element earns its space.
 *   - Responsive. Works on the phone in your pocket.
