/* ══════════════════════════════════════════════════════════════════════════
   auth-v3.css — sign-in (login.html) and sign-up (signup.html).

   Load order: plenum.css (Airflow tokens + base) → theme-auth.css (the colour
   tokens this page adds, and the .au-inverse panel palette) → this file.
   Colours come from tokens only; spacing shorthands use --sp-* (plenum) or the
   --au-* steps below, so this sheet adds nothing to the lint:css ratchet.

   The old layer, auth.css, stays for portal.html, which still uses it.

   Composition: an INSET showcase panel on the left, always the inverse of the
   page ground, with a quiet airflow field behind it and the customer record in
   front; the task sits on the page ground on the right, with no card around it.

   Motion: everything user-triggered animates; the only ambient motion is the
   airflow and the record loop on sign-in, both gated on html.motion (set before
   paint unless prefers-reduced-motion), and the loop pauses while you type.

   NAMESPACE: plenum ships .stat, .stage, .pop, .av, .bar, .n and scoped .ic /
   .amt / .dot / .sub / .d. The names here avoid the unscoped ones (.rstat,
   .panels, .node-pop, .who-av, .seg-bar, .seg-n) — check a new class against
   plenum before using it; .foot and .empty have both bitten this page before.
