Subject: [PATCH] TASK 58: the properties panel wears the theme (no more
 light-system chrome)

The creator asked why the Stream Alerts "Display" drop-down was not in the same
style as the other drop-downs. It was never given the theme's YtComboBox style -
only a hand-painted Background/Foreground. Setting colours changes the paint, not
the template, so WPF still drew the light system ComboBox (grey border, system
arrow, white popup list) on top of the dark panel. The chat Font drop-down was a
copy of the same mistake, and every check box was the light system one.

The sweep of the whole properties panel (then the app):
  - ComboBox x2 (chat Font, alert Display) -> YtComboBox, hand-painted colours gone
  - TextBox x16 in the properties panel -> YtTextBoxCompact (new, BasedOn YtTextBox:
    11px / padding 4,2 - the panel is dense, the full 13px box would double it)
  - CheckBox x2 (chat) + x3 (preview broadcast) + x1 (socials dialog) -> YtCheckBox
    (new: a 14x14 rounded box + tick path, accent fill when checked)
  - the layer-rename field -> YtTextBoxCompact via BasedOn, still borderless
  - buttons, pills, sliders: already themed, untouched

The sweep also killed a typo'd foreground (#e0d0e0 for #e0e0e0) and the only
remaining hand-painted colour is the deliberate dimming of the two read-only path
fields.

Guard: ytLive.Tests/PropertiesStyleTests.cs (the ONE Good Dog test) parses the app
XAML and fails if an unstyled drop-down, check box or properties field comes back.

+## 2026-10-21 — A WPF CONTROL WITH NO STYLE DRAWS THE LIGHT SYSTEM CHROME (RECIPE — TASK 58)
+
+The creator asked why the Stream Alerts "Display" drop-down looked like it belonged to another
+app. The cause is not a colour: **setting `Background`/`Foreground`/`FontSize` on a WPF control
+changes its paint, not its TEMPLATE.** An unstyled `ComboBox` still renders the system template —
+grey border, system arrow, **white popup list** — so a dark blue box sat on the dark panel
+wearing light-system chrome. Unstyled `CheckBox` is the same story.
+
+**The recipe (audit + fix + guard):**
+1. **Audit by grep, not by eye:** `grep -rn "<ComboBox\|<CheckBox" --include="*.xaml"` and look at
+   each one's `Style` attribute. Hand-painted colours are the smell — they mean "no style".
+2. **Fix by style, never by more painting:** put the look in `Themes/Controls.xaml` once
+   (`YtComboBox`, `YtCheckBox`, a `BasedOn` compact variant when the panel is dense) and delete
+   the per-control colours. A dense panel needs a *variant* of the style, not a re-painted control.
+3. **Guard it with a test** that parses the XAML and fails when a control of that type has no
+   style — otherwise the next hand-painted control walks the look back.
+4. **Check the inherited defaults while you are there:** a compact `BasedOn` variant must set the
+   metrics it overrides (`FontSize`, `Padding`, `MinHeight`) or the panel silently changes density.
+
+**Side effect worth naming:** the sweep also exposed a typo'd foreground (`#e0d0e0` instead of
+`#e0e0e0`) that only a single source of truth can prevent from recurring.

+# TASK 58 — Properties-panel style consistency (the theme owns the look)
+
+**Status:** ✅ Done — shipped 2026-10-21.
+
+## What it is
+The creator asked (2026-10-21), pointing at the Live scene → Stream Alerts layer →
+Properties → **Display**:
+
+> why is the drop-down box not in the same style as the others? Can you run through the
+> existing elements in properties to ensure that we're maintaining a consistent style?
+
+## Why the drop-down looked alien
+`Controls/LeftPanel.xaml` gave the drop-down a hand-painted `Background`/`Foreground`/
+`FontSize` instead of the theme's `YtComboBox` style. Setting colours does **not** change a
+control's template — WPF still drew the **light system ComboBox** (grey border, system
+arrow, white popup list) on top of the dark panel. The code even said so: the alert
+drop-down's comment says it was built "same shape as the chat Font selector above" — and the
+chat Font drop-down was unstyled too, so the inconsistency was copied.
+
+## The sweep (the whole properties panel, then the app)
+| Control | Before | After |
+|---|---|---|
+| ComboBox ×2 (chat Font, alert Display) | hand-painted colours → light system template | `YtComboBox` (the same style as the bottom-bar/zoom drop-downs) |
+| TextBox ×16 in the properties panel | hand-painted colours, no template, no focus/hover, one typo'd foreground `#e0d0e0` | `YtTextBoxCompact` (BasedOn `YtTextBox`: 11px, padding 4,2) |
+| CheckBox ×2 (chat) | default light system check box | `YtCheckBox` (new dark style) |
+| CheckBox ×3 (preview broadcast panel) + ×1 (Socials dialog) | default light system check box | `YtCheckBox` |
+| TextBox (layer rename) | hand-painted colours | `YtTextBoxCompact` via `BasedOn`, borderless as before |
+| Buttons, pills, sliders | already themed | unchanged |
+
+New theme styles (`Themes/Controls.xaml`):
+- `YtTextBoxCompact` — `BasedOn YtTextBox`, 11px + `Padding 4,2` + `MinHeight 22`. The
+  properties panel is dense (11px labels); the full `YtTextBox` (13px, 8,6) would have
+  doubled the panel's height.
+- `YtCheckBox` — a 14×14 rounded box + tick path, accent fill when checked, hover/focus
+  border triggers. The default WPF check box is the light system one.
+
+## The guard
+`ytLive.Tests/PropertiesStyleTests.cs` — the ONE test for this change:
+1. the theme defines `YtComboBox`/`YtCheckBox`/`YtTextBox`/`YtTextBoxCompact`;
+2. every `ComboBox` and `CheckBox` in the app's XAML carries the matching theme style;
+3. every field in the properties panel (`StackPanel x:Name="ElementsPanel"`) carries
+   `YtTextBoxCompact` and sets no `Background`/`BorderBrush` of its own.
+
+## Tests
+`ytLive.Tests/PropertiesStyleTests.cs` — 431/431 green at ship time.

@@ -276,7 +276,7 @@ C# / WPF (.NET 8) following MVVM:
 - Layout persists to SQLite (`Microsoft.Data.Sqlite`); scenes/sources/asset bytes stored in the DB, asset identity is a SHA-256 content hash (1:M reuse, no file paths — assets are always available). Loaded sources always derive `IsBackground` from `Type` (OR'd with the persisted column, so legacy DisplayCapture backdrops keep their flag) — pre-derivation rows with `IsBackground=0` heal on load
 - **Element z-order is a unified space, not per-table (2026-09-20):** `Source` and `WebcamSceneConfig` live in different tables, and a webcam can be interleaved between sources in a scene. Both tables' `SortOrder` is stamped from the SAME counter — the element's index within `scene.Elements` — and `Load` merges the two tables' rows per scene by that shared z (tie-break sources-first, so legacy per-table rows read back stacked the way they were saved). Never re-introduce per-type sort counters + "append all Sources then all configs", or a webcam slotted mid-stack reverts on reload (creator-reproduced bug).
 - **Five-scene catalog (`Models/SceneCatalog.cs`):** the product is exactly Starting/Live/BRB/Chat/Ending — work with less, never more (the escape hatch for "more" is OBS). Scenes are matched **by name** (`SceneCatalog.Is`, case-insensitive trim). Empty DBs seed all five; the scenes-header "+" (`ShowAddScene`/`MissingScenes` on `MainViewModel`) only appears while ≥1 canonical scene is missing and its menu lists only the missing ones, re-adding them by name (`AddSceneCommand`). Renaming a canonical scene makes it missing again; `AddScene` rejects non-canonical names.

+- Theming: all custom styles live in `Themes/Controls.xaml`, merged in `App.xaml` — never duplicate styles per-window (dialog duplicates were consolidated into this dictionary). **Every control in the app carries a theme style (TASK 58, 2026-10-21):** an unstyled `ComboBox`/`CheckBox` falls back to the **light WPF system template** (grey border, system arrow, white popup list) and sticks out of the dark panels — the properties panel's drop-downs had been hand-painted with a `Background`/`Foreground` instead of a style (the chat Font drop-down was a copy of that), and every check box was default. The rule now: `ComboBox` → `YtComboBox`, `CheckBox` → `YtCheckBox`, the dense properties fields → `YtTextBoxCompact` (`BasedOn YtTextBox`: 11px, padding 4,2) — **no hand-painted `Background`/`BorderBrush` on a themed control**. `ytLive.Tests/PropertiesStyleTests.cs` is the guard: it fails if an unstyled drop-down, check box or properties field comes back
 - Resolution tiers: 1080p60@8 (default) → 1080p30@8 → 720p60@6 → 720p30@6 → **Vertical 1080p60@8 (9:16, 1080×1920)**. The composition master frame is **always 1920×1080** — a tier is an output rect + target resolution over that master, so source geometry is never rewritten (no rounding drift). 16:9 tiers use the full frame; the vertical tier uses a centered **607×1080** window and the preview dims the cropped side strips at 55% black with an accent outline (semi-crop — the cut area stays visible). A resolution badge in the preview corner shows the active tier. Bottom bar: gear icon far left, stream stats (bitrate/FPS/dropped/duration) centered under preview, resolution dropdown far right. A **tooltip** explains finding upload bandwidth — an in-app speed test was deliberately dropped (unreliable). The future encoder crops the master to the rect and scales to the tier's Width×Height
 - Crash diagnosis: `AppLog` writes startup checkpoints to `%APPDATA%\ytLlive\startup.log`; `App.xaml.cs` logs `DispatcherUnhandledException`/`AppDomain.UnhandledException`. When WPF won't run from WSL, this log is how you find the failure (it caught the `MenuItemRole.Separator` XAML crash and the ComboBox SelectionBoxItem bug)
