/* ============================================================
   One Continuous Cosmos — homepage below-hero revamp
   A single aurora ground + editorial system (eyebrows, dividers,
   numbered step ledger, instrument stats, device "signal arrives"
   wave) that carries the hero's language down the whole page.
   All classes are .tr-* (purged Tailwind bundle can't add utils).
   Motion: one-shot reveals + minimal ambient. No scroll-scrub.
