/*
  Auth surface styles. Shared by /login (public/login.html) and /signup
  (public/signup.html, public/signup-check-email.html). Ported verbatim
  from demo/demo-atelier/css/style.css (the :root variables, base reset,
  and .login-* rules). Class names keep the .login-* prefix from the
  demo even though signup reuses them — cosmetic naming only.

  This file is plain vanilla CSS — no Tailwind, no @apply, no @theme, no
  @layer. The demo is plain CSS too, so byte-identical render is the goal.

  Source mapping:
    :root           -> demo style.css lines 1-24
    base reset      -> demo style.css lines 26-55
    .login-* rules  -> demo style.css lines 57-283 (omitting .login-hint)
    @media <980px   -> demo style.css lines 1517-1519 (login-only subset)
    .login-signup-link -> NEW rule (not in demo; for the
                         "New here? Create your workspace" link)

/* Anchor the form to the TOP of the column (was `safe center` shared,
   then incorrectly `place-items: safe start` here) so the title sits
   close to the lang-toggle instead of being vertically centered.

   The axes are split intentionally:
   - `align-items: safe start` — block axis only. Anchors the form to
     the top of the column.
   - `justify-items: center` — inline axis. Keeps the form horizontally
     centered in its column, exactly like /login's shared
     `place-items: center`. Without this, `safe start` on both axes
     glues the form to the inline-start side of its column — in LTR
     that's the form's LEFT edge butting up against the brand-panel
     boundary, which reads as the brand panel "extending further" than
     on /login. The block-end column is the form column on both pages
     identically; this rule only affects the form's position WITHIN
     that column.

   `overflow-y: auto` remains as a safety net so the column scrolls
   internally on very short viewports. */

/* ============================================================
   Shared auth toast (used by both /login and /signup).
   ============================================================

   .auth-submit-row is a positioning context for the absolutely-
   positioned .auth-toast. Wrap the submit button in this row on
   both pages; the toast anchors to the row's top edge via
   `inset-block-end: calc(100% + …)`. The row has no styling beyond
   `position: relative` — it exists purely so the toast can anchor
   without depending on the form column wrapper's geometry.

   .auth-toast is the floating error surface. Absolutely positioned
   above the submit button so it overlays without displacing the
   button, fields, or the footer link. Driven by login.js /
   signup.js: showXxxToast() adds .show, hideXxxToast() removes it.
   Hover pauses the auto-dismiss timer; mouseleave restarts a fresh
   5.5s window.

   The visibility transition uses a 0.28s delay on hide so opacity
   has time to fade out before visibility flips to hidden; on show,
   the visibility delay is zero so the element appears instantly
   while opacity and transform animate. translateY (not translateX)
   keeps the slide direction RTL-independent; scale(0.98) at the
   start adds a subtle "lift" as the toast rises into place.

   Palette: cream surface, burnt-orange (--accent) inline-start
   stripe, navy text, --shadow-lg for the elevated feel. Logical
   properties throughout so RTL mirrors automatically. */
