/* ---------- /login — themed session entry (v0.16) ----------
   Reuses style.css's tokens (--ph/--acid/--mono/etc), .crt-grid and .scan
   from the main sheet for a consistent phosphor-CRT feel; everything below
   is scene-specific layout + the passphrase prompt + denied/success beats.
   Two-green rule holds here too: acid marks the caret and the live sweep
   only — everything else stays in the dim/ambient tier. */
