/* ui2-components.css — Reusable UI2 visual primitives.

 * Class names use `ui2-` prefix to avoid colliding with any prod CSS that

 *
 *   1) ui2-fonts.css
 *   2) ui2-tokens.css      (defines --ui2-* vars)
 *   3) ui2-components.css  (THIS file; consumes vars)
 *   4) <page>.css          (page-specific layouts)
 *
 * Every selector is scoped under `body.ui2` so this stylesheet is inert
 * on pages that haven't opted in.

/* ─── Reveal-on-scroll ──────────────────────────────────────── */

/* HISTORY: An earlier version of this file set
 *   body.ui2 .ui2-reveal { opacity: 0; transform: translateY(12px); ... }
 * with `.visible / .is-visible` to restore opacity:1. That broke prod
 * pages where /shared/ui2-interactions.js auto-tags many elements
 * (.hero, .plan, etc.) with `.ui2-reveal` for its OWN scroll reveal
 * system. Those elements ended up stuck at opacity:0 because the
 * interactions.js toggle didn't always end on a class our selector
 * recognized.
 *
 * Fix: do NOT default `.ui2-reveal` to opacity:0 globally. Defer the
 * reveal mechanic entirely to /shared/ui2-interactions.js (prod's
 * existing system) and the fadeUp keyframe animations baked into
 * page-level inline styles. ui2-fx.js's initReveal() still adds
 * `.visible` for opt-in elements that explicitly want our system, but
 * the visibility transition is now ADDITIVE to prod styles, not a
 * mandatory hidden-by-default override.
 *
 * If a page truly wants the UI2 hidden-then-fade-in pattern, opt in
 * with the explicit `.ui2-reveal-init` class and our fx.js handles it. */

  opacity: 0;

/* Nav auth-state populator safety net.
 * Prod page inline CSS:  .nav-actions{opacity:0} + .nav-actions.ready{opacity:1}
 * On some pages (/free-tools, /blog) the .ready class is added but the
 * computed opacity stays at 0 — root cause is timing-related (transition
 * starting before CSS finishes parsing on subsequent loads). Force the
 * winning state with !important so the auth-rendered nav buttons / user
 * pill never disappear. */
