/*
 * Critical Bootstrap 5.3 Grid + Layout (self-hosted fallback)
 * ============================================================
 * Contains ONLY the grid system, display/flex/spacing utilities,
 * and reboot basics that your templates actually use.
 *
 * Loaded BEFORE the CDN Bootstrap. If CDN fails, layout still works.
 * If CDN succeeds, it overrides these rules with identical specificity.
 *
 * Size: ~10 KB (vs ~200 KB full Bootstrap)
 * Generated from Bootstrap 5.3.2 source
