/* ===========================================================================
   price-insights.css — the price-persuasion strip + price-history modal
   Release 2 of the price logger. Component styles lifted from the approved
   mockup (docs/plans/price-insight-mockup.html); demo-only chrome (phone
   frames, states gallery, callouts) dropped.

   THEMING NOTE — deliberately light-only.
   The mockup ships light + dark, but nopturnia.com has *no* dark mode: there
   is not one `prefers-color-scheme` or `data-theme` rule in css/. Honouring
   the mockup's dark block here would render a dark strip inside a permanently
   light card. So every surface colour derives from the site's own `--v2-*`
   tokens (with fallbacks, for legacy pages that only load style.css), and the
   semantic status colours — which the site doesn't define — are declared once
   below. The day blog-v2.css gains dark tokens, the strip follows on its own;
   the staged dark block at the bottom is all that needs uncommenting.

   Everything is namespaced `pi-` / `pi-modal-`: this file loads on pages that
   already own generic names like .modal and .stat.
