/* ============================================================
   components.css - Reusable UI building blocks
   ------------------------------------------------------------
   Goal: define each reusable element ONCE as a class. The HTML
   only composes these classes - no block re-styles them and no
   raw values are hardcoded (everything is a var(--…) token).

   Contains: buttons + button row, full-width strip, fine print,
   the status pill, the feature card, the industry card (incl.
   its slideshow layers, shared by hover and touch via the
   JS-toggled .is-playing class), the FAQ accordion item, the
   live transcript popover, the mobile-nav hamburger button, and
   the cookie consent banner (dormant).

   Each component is self-contained: its own responsive and
   reduced-motion rules sit next to the component, so it can be
   reused without hunting down media queries elsewhere. Authored
   MOBILE-FIRST (base = phone; min-width enhances; breakpoint
   scale documented in tokens.css).

   Depends on: tokens.css (loads after base.css, before sections.css).
