/* File: /assets/css/premium.css
   Module: /premium/ (page-premium.php)

   Color grammar: royal blue is Premium, both its marks (the "Pro" chip, the
   Premium column) and, since 2026-10-03, its buttons: every .ch-prem-btn is
   the sitewide Premium button (style.css :root --ch-pro-*), because this page
   has one action and it buys Premium. Emerald stays the color of links and
   checks here. The store-apps band is the deep DevSecOps surface that stays
   identical in both themes.

   GeneratePress styles every button:hover / :focus / :active with a dark
   background at specificity 0,1,1. Every button state below is declared at
   0,2,0 or higher so none of them flashes dark grey on hover.

   Contents: 1 tokens, 2 layout + type, 3 buttons, 4 hero + plan card,
   5 tiles, 6 store apps, 7 table, 8 billing facts, 9 FAQ, 10 closing band,
   11 toasts, 12 responsive, 13 dark, 14 reduced motion */
