/* =============================================================================
   Sedra5 base components
   Shared building blocks used across the public and admin pages: buttons,
   forms, tables, modals, badges, pagination, content pages. Built only from
   theme tokens (themes/<theme>/theme.css), so they follow dark/light mode
   and any theme without changes.
   Load order on every page: theme.css, reset.css, layout.css, syriac.css,
   components.css, then pages.css (public) or admin.css (admin) - so page
   styles can refine Syriac text without fighting syriac.css specificity.
