/* ===== OPENING ANIMATION (usbio-intro) — START ===== */
/* ==========================================================================
   OPENING ANIMATION — adapted from Fortified Asset Solutions' "collapse to
   shield" v2 (source: 21_STONECUTTER_full-no-video_2026-08-08/21_STONECUTTER/
   source/FORTIFIED_ASSET_SOLUTIONS copy/04_Website_V3/assets/css/main.css,
   owner-approved 2026-08-02). 2.0s total, transform/opacity ONLY so
   #usbio-intro can never become the LCP element and can never reflow the
   hero underneath it. contain:strict isolates it from page layout.

   THREE RULES THIS BLOCK OBEYS (same three FAS obeys — do not break any):
     1. LCP-SAFE. The real hero is in-flow DOM at opacity 1 from first paint.
        #usbio-intro is a position:fixed sibling painted OVER it.
     2. REDUCED MOTION goes straight through — never rendered, never played.
        The global rule near the top of this file (prefers-reduced-motion)
        kills animation/transition properties but NOT display, so the scoped
        rule at the bottom of this block is required — without it a
        reduced-motion visitor would see a frozen navy field stuck on screen.
     3. PLAY-ONCE, no storage APIs. See the inline <script> at the top of
        index.html for the in-memory guard + referrer/navigation-type check.
   ========================================================================== */

/* FAIL-OPEN DEFAULT. display:none until the inline controller on the
   homepage decides to play it and adds .armed. If that script is blocked,
   throws, or never runs, the visitor sees the hero — never a navy field
   stuck over the site. This is the single most important rule in this block. */

   TIMELINE — 2.0s total. SETTLE_AT=1580ms / TOTAL_MS=2000ms below must stay
   in sync with the same two constants in the inline <script> in index.html —
   same clock.

     0.00 - 0.42   US / BIOLONGEVITY rise in, stacked, 130ms stagger
     0.36 - 0.74   COLLAPSE — every letter converges to the viewport center
                   and fades. No survivors.
     0.68 - 1.06   Logo mark stamps in dead center (scale 0.55 -> 1.06 -> 1.0)
                   with an expanding, fading cyan ring. No jolt, no dust —
                   clinical tone.
     1.00 - 1.58   Thin cyan rule draws left-to-right under the mark, holds,
                   fades right before the glide.
     1.30 - 1.58   HOLD — 1.0 -> 1.015 -> 1.0 breathe on the mark.
     1.58 - 2.00   GLIDE — measured glide onto the header's own logo image;
                   the navy field cross-fades ONLY after the glide lands —
                   fading earlier would double-image the two logos.
