   TOAST NOTIFICATIONS — drop-in component (giixi)
   Source design: design-pkg/live-roi/project/Toasts.html
   Used everywhere: Django messages, JS notifications, errors.

   NOTE: Every rule is scoped under `.toast-stack` so that
   Bootstrap 5's own `.toast` class (which sets display:none
   and a fixed width on bare `.toast`) cannot override us.

/* ============================================================
   LIGHT THEME OVERRIDE
   ponytail: light override only — dark block above stays the
   default and byte-identical. The dark rules bake DARK literal
   fallbacks into var() (e.g. var(--panel-2, #202023)), so under
   light we can't just redefine tokens; we restate the few rules
   that carry hardcoded dark literals with light values. The 4
   --toast-* kind hues stay as DECORATIVE accents (progress bar /
   chip tint / btn fill+border). But two usages put a kind hue on
   white where it fails WCAG contrast: the action-button LABEL TEXT
   (.toast__btn) needs >=4.5:1 and the kind-indicator GLYPH
   (.toast__icon svg) needs >=3:1. On white the raw hues are far
   too light (warning ~1.9:1, success ~2.1:1), so for light theme we
   darken those chromatic foregrounds toward #18181b via color-mix.
   Shadows re-anchored lighter.
