Cross-cutting polish that surfaced while Phase 8 was being implemented:
* Invariant-culture formatting on every decimal ToString("0.00" / "0.##")
(OddsCell, OddsTimeline, SeverityBadge, AnomalyEvidence,
Pages/Events/Detail) — previously the comma/dot decimal separator
switched with the locale and broke tabular alignment + tests.
* LocaleState constructor no longer mutates process-wide ambient culture;
apply only happens through Set(...). Stops parallel bUnit test runs
leaking ru-RU into each other's threads.
* MainLayout: drawer-open state now offsets main content / footer / appbar
by the drawer width (248px) so the sidebar no longer overlaps content.
Mobile breakpoint (≤720px) keeps the original full-width layout.
* wwwroot/index.html (Marathon.UI RCL): switched from Plotly CDN to the
bundled "_content/Plotly.Blazor/plotly-2.35.3.min.js" — works offline
and matches the Plotly.Blazor 5.4.1 version pin.
* Marathon.Hosts.WpfBlazor/wwwroot/index.html: host-level page that
BlazorWebView's HostPage attribute resolves to. Same Plotly bundle,
no autostart="false" (BlazorWebView auto-starts).
Three fixes surfaced when launching the WPF host for the first time:
1. App.xaml.cs — call MarathonDbContextInitializer.InitializeAsync()
between Host.Build() and Host.Start() so EF migrations + WAL pragma
are applied BEFORE BackgroundServices race to query the DB. Without
this, all pollers crashed on 'no such table: Events'.
2. wwwroot/index.html — added <script src='https://cdn.plot.ly/plotly-2.35.2.min.js'>
before blazor.webview.js. Phase 6 reviewer flagged this for Phase 9,
but charts are unrenderable without it; better to ship now.
3. Migrations/20260505000000_InitialCreate.cs — added [DbContext] and
[Migration('20260505000000_InitialCreate')] attributes. Phase 2's
hand-written migration was missing both, so EF saw 'no migrations to
apply' even on a fresh DB. With the attributes, the migration runs
on first launch and creates all tables (Events, Snapshots, Bets,
EventResults, Anomalies, Sports, Leagues).
Verified: clean DB → migration applied → all 7 tables created → pollers
run with empty results (no data yet — UpcomingEventsPoller fires every 6h
by default; first scrape will populate the DB).
Per Phase 1 reviewer notes — strips Component1.razor, ExampleJsInterop, and
the wwwroot template assets generated by 'dotnet new razorclasslib'. Phase 5
will populate Marathon.UI from scratch with the real layout, components, and
wwwroot/index.html for BlazorWebView. Build still green (0/0).
Creates the 9-project .NET 8 solution (5 src + 4 test) with Marathon.Domain
fully implemented: value objects (SportCode, EventId, OddsRate, OddsValue,
BetScope hierarchy), enums (Side, BetType, OddsSource, AnomalyKind), and
entities (Sport, Country, League, Event, Bet, OddsSnapshot, EventResult,
Anomaly) with all invariants enforced in constructors. 96 domain tests pass
(FluentAssertions + xUnit). Directory.Build.props and Directory.Packages.props
centralise build settings and NuGet versions. Both Marathon.sln and Marathon.slnx
are committed; dotnet build Marathon.sln succeeds with 0 warnings/errors.
