/**
 * cf-blocks.css
 * ─────────────────────────────────────────────────────────────────────────
 * Runtime styling for Page Builder blocks that need CSS, not just JS, to
 * actually work: Columns, Tabs, Drawer, and scroll-reveal animations.
 * Referenced by both the canvas iframe (app.js) and every published page
 * (worker.js) — must ship at /css/cf-blocks.css on both.
 *
 * Without this file:
 *  - Tabs: every panel has the SAME specificity/display as the active one,
 *    so all panels show at once instead of only the active tab.
 *  - Drawer: the panel and backdrop are position:fixed with no default
 *    hidden state, so they render open/visible immediately regardless of
 *    whether .cf-drawer-open has been toggled on yet.
 *  - Columns: .cf-cols/.cf-cols-2/3/4 have no grid rules, so columns
 *    stack as plain divs instead of laying out side by side.
 *  - Scroll animations: .cf-anim/.cf-in-view (toggled by interactions.js)
 *    have no opacity/transform rules, so the reveal never visibly happens.
