/* Karamatics components, v2 ("Cobalt"): buttons (with pressed and toggle states), navigation (with dropdowns),
 * theme toggle, hero backdrop, quotations, chips, badges, cards, tabs, segmented switches, forms, alerts and footer.
 * Requires tokens.css and base.css. Class names follow v1, so a page moves over by swapping its links; v1's .btn-ghost
 * is kept as an alias of .btn-secondary. Page-specific layout (grid columns, headline sizes) stays with the page.
 * press.js adds the ripple on press; without it buttons still sink and darken. */
