/* Atlas header lockup: wavy seal (globe, which dissolves to the Earthbar "e" then the Beaming "b") + "atlas" wordmark.
   Final approved design (no-ring variant), from the animated source R4SealNoRing. Everything is inline SVG; only transform and opacity animate.
   Loop: border turns 48s linear; three meridians sweep (scaleX) every 3.6s staggered; every 10s the globe fades to the e (19-31%) and to the b (69-81%).
   Static mark (prefers-reduced-motion) = seal + still globe, no e/b. Paused while the tab is hidden (atlas-logo.js). See docs/atlas-logo.md. */
