/*
 * EVSA Main Stylesheet

 * CSS architecture: modular imports + per-page stylesheets.
 * Core modules are imported here; components.css and per-page CSS
 * (calidad.css, solucion-e2e.css, etc.) are loaded directly in each
 * HTML file with cache-busting query params (?v=XX).
 *
 * Load order: tokens → base → layout → (this file) → components → hero → per-page
