/* ══════════════════════════════════════════════════════════════════════════
   Auth pages (login / register) — premium AI trading theme

   Reads the shared --dash-* palette from dash-tokens.css, which the auth
   layout links just before this file. Same tokens the dashboard uses, so the
   two surfaces stay in step: change a token there and both re-skin.

   Layout note: .auth-modern is the page wrapper; the form sits in a single
   .card that the layout renders. Everything here is scoped under
   .auth-modern so the stock Sneat auth CSS is only overridden on these pages.

/* ── Page canvas ──────────────────────────────────────────────────────────
   Layered bottom-to-top: flat black base, two wide pools of blue/purple
   light, then the artwork. The overlay gradient sits ABOVE the photo so the
   card never has to fight a busy background for contrast.

   The background photo is optional — until the file exists the gradients
   alone already render the intended look, so a missing image degrades
   cleanly rather than showing a broken page. */
