/* ============================================================
   FLUXATH CRM — Stripe-inspired form primitives
   (Phase 2A of stripe-reskin-2026-05-24)

   Scope: buttons (.btn, .btn.primary, .btn.subtle, .btn.danger,
   .btn-pill, .btn-sm), text inputs / textareas / selects,
   checkboxes, radios, toggle switches.

   Rules consume tokens from tokens-stripe.css (--rad-*, --ease-*,
   --shadow-soft-blue-*, --type-button-*). Color tokens stay sourced
   from style.css (--brand, --accent, --ink, etc.) so the FLUXATH
   palette + 12 accent themes + dark/light base survive intact.

   NO template logic edits. NO data-action wiring changes. CSS only.
