Credentials drawer code-block labels (printable:, b64:) and a
dozen other violet wash/tint sites still carried bare rgba(238,
130, 238, *) literals — bright magenta in light mode where
--violet has resolved to charcoal-purple #2d1b4e. Mirrors the
prior matrix/alert/warn/info sweeps: by-alpha buckets land on
var(--violet-tint-10) or var(--violet).
- Modal: shared backdrop/panel with ESC-close, backdrop-click-close,
focus trap, body scroll lock; supports center + drawer-right variants,
matrix/violet accents, default/wide widths.
- EmptyState: icon + title + hint + optional CTA; compact variant
for tight rails.
- useEscapeKey, useFocusTrap: reusable hooks powering Modal; will also
be adopted by CommandPalette and ContextMenu in follow-up commits.
No retrofits yet — primitives only. tsc clean.
