The per-element color/box-shadow transition repainted the whole tree every frame (~5fps). Replaced with document.startViewTransition: the browser cross-fades one GPU-composited snapshot of the page — smooth regardless of element count. flushSync + useLayoutEffect ensure the data-theme flip is captured in the transition; instant fallback where unsupported / reduced-motion.

ThemeContext adds a .theme-transition class to <html> for ~300ms during a real toggle (skipped on initial mount); a scoped base.css rule applies a uniform 0.3s color/bg/border/fill/stroke/shadow transition to the whole tree only while that class is present — so the entire UI fades together on switch, while normal interactions keep their own transitions. Respects prefers-reduced-motion.

Removed MuiColorSchemeSync: it called MUI setMode which ALSO wrote data-theme, fighting ThemeContext (the other writer) → theme flip-flop loop. ThemeContext is now the sole owner; MUI's cssVariables CSS (scoped by [data-theme]) applies from the attribute, no JS bridge needed. New animated ThemeToggle kit button (sun/moon crossfade+rotate) replaces the static AppShell toggle. DashAttendanceToday avatars now solid-fill + white initials (matches StatCard/activity badges).

Replaces admin-* CSS, ConfirmModal, and legacy markup with PageHeader,
Card, DataTable, ConfirmDialog, StatusChip, EmptyState, LoadingState.
Dual StatusChip badges per row: leave-type (info/error/default) and
status (warning/success/error/default). Note cell preserved with Box
title-tooltip and ellipsis truncation. cancelMutation and invalidate:
["leave-requests", "leave", "attendance"] preserved verbatim.

DataTable: optional per-column width; when any column sets one, the table uses table-layout:fixed with a colgroup so columns keep a stable size instead of reflowing as rows are filtered (overflow clipped with ellipsis). Tables without widths keep auto layout. Projects: assign column widths; restore the original '(přiděleno automaticky)' suffix on the next-number hint.

previewSharedNumber returned applyPattern(previewNextSequence) directly. When the number_sequences counter lags behind real data (e.g. orders/projects imported or seeded without bumping it), that raw next sequence is already taken, so the create-project modal showed an already-used number (e.g. OBJ-2026-001) even though generateSharedNumber would correctly assign the next free one via its collision-check loop. Mirror that loop in the preview (without consuming the sequence) so the hint matches what will actually be assigned. Adds two numbering tests.

Documents the in-progress CSS->MUI migration (spec/plans, page-migration pattern, kit, gates, dialog gotchas) and the convention to keep the agent-memory progress tracker (project_mui_migration.md) updated as phases merge.
