/* ============================================================
   WP Booking Plugin — Public CSS

   Every token is pulled directly from the project's style.css
   (Tailwind v4 build). Palette, radius, fonts, text sizes,
   spacing scale (--spacing: 0.25rem) all match.

   Rules are scoped under .wpbp-container; defensive resets at
   the top stop theme styles (e.g. brand text colors on buttons,
   underline on a tags) from leaking in. Every value is explicit —
   no cascade keyword is used anywhere in this file.
