djust 0.5.1rc2

Scaffold CSS — reusable layout/utility pack in djust.theming — djust_theming/static/djust_theming/css/scaffold.css gains ~729 lines of framework-generic scaffold covering typography, responsive grid utilities (.grid-2/3/4), hero section, flash messages (Django + LiveView), accessibility utilities (.sr-only), extended layout helpers (.flex-center, .content-narrow/-wide), stat-display variants, auth layout, live indicator dot, card-accent variants, code blocks, noise texture overlay, shared nav links, dashboard/centered grids, and the full data-layout switching system (sidebar, topbar, dashboard, centered, sidebar-topbar). All new rules use CSS-variable fallbacks so the scaffold works without a loaded theme; no hardcoded hex colors; .container max-width now reads var(--container-width, 1200px). Pure-CSS addition — no Python/JS/test behavior changes. (PR #836)

• Test-infrastructure shims (64 fixes) — added tests/gallery_test_urls.py and tests/test_critical_css.py URL-conf shims that theming tests reference via @override_settings(ROOT_URLCONF=...) but were never created; added mcp[cli]>=1.2.0; python_version >= '3.10' to dev deps so djust.mcp server tests stop throwing ModuleNotFoundError.
• Stale @layer test expectations (4 fixes) — several theming CSS files (components.css, layouts.css, pages.css, critical-CSS generator) were intentionally unwrapped from @layer blocks for specificity reasons (documented in file headers); updated tests to match the current design using @layer NAME { block-syntax regex rather than substring match.
• Real code bugs (3 fixes) — ocean_deep preset's internal name was "ocean" while its registry key was "ocean_deep"; one stray text-align: left in components.css.tp-select-option broke RTL support (changed to text-align: start); and the CSS prefix generator's hand-maintained _COMPONENT_CLASSES list had drifted from components.css — .btn-edit, .btn-remove, .avatar, .breadcrumb, .dropdown and many more weren't being prefixed when a custom css_prefix was set. Replaced with auto-extraction via regex over the static file; stays in sync automatically.
• Stale test assumption (1 fix) — test_list_same_content_no_render encoded a wrong assumption about _snapshot_assigns (identity-based by design); rewrote to match the documented contract.
