/* ============================================================================
   TARA — skin-aurora-shell.css (Phase 2 — logged-in app shell, UI "aurora").
   DERIVED from ../S43-login-previews/light-A-aurora.html (login-only final):
   pastel aurora page atmosphere, glass sidebar card, rounded soft shadows,
   Inter type, indigo→teal→rose accent gradient. Palette/tokens mirror the
   Phase-1 sibling skin-aurora.css so gate + shell read as ONE design.
   Every selector is scoped under html[data-ui="aurora"]. CSS only, no new DOM.
   #gate / .gp-* / .gate-* are untouched (Phase-1 file owns those).
   No @keyframes are declared here at all (weak-GPU rule: the atmosphere is
   static gradients only) — the tsh-/ash- prefix rule is therefore trivially met.
