/* app.css — styling for the vanilla shell (index.html): home view, app
   toolbar/tabs/chip bar, Table View, Relationships, modals. Every value
   comes from tokens.css (the Wise design system — see DESIGN-wise.md);
   component names follow DESIGN-wise.md's components block (card-content,
   card-feature-green, button-primary/secondary/tertiary, hero-band, ...).
   synth-sql kept this inline in synth.html; it's a separate file here so
   the static pages and the island can reuse the same primitives.
   The dashboard island's own styles live in dashboard/src/. */
