/* ============================================================================
   PRAVAHA COMPONENTS — FITCO Design System v4
   Version 4.1.0 | 2026-07-07 | Split from pravaha.css (v70 -> v71 breakaway)
   The .p-* component library (.p-page base, buttons, cards, stats, tables,
   forms, CTA, pagination). Everything here is scoped under .p-* classes.
   Requires css/pravaha-tokens.css (loaded globally by the theme).
   Enqueued ONLY on routes whose markup uses .p-* classes
   (currently: home, our-products). Do not enqueue globally.
