P2: Android parity gallery — real-screen captures (partial, 17/40 surfaces)

Replaces the synthetic theme-showcase ScreenshotTests with real screens
rendered against FixtureDataManager.empty() / .populated() via
LocalDataManager. GallerySurfaces.kt manifest declares 40 screens.

Landed: 68 goldens covering 17 surfaces (login, register, password-reset
chain, 10 onboarding screens, home, residences-list).

Missing: 23 detail/edit screens that need a specific fixture model passed
via GallerySurfaces.kt — tracked as follow-up in docs/parity-gallery.md.
Non-blocking: these render silently as blank and don't fail the suite.

Android total: 2.5 MB, avg 41 KB, max 113 KB — well under the 150 KB
per-file budget enforced by the CI size gate.

+/**
+ * Declarative manifest of every primary screen in the app that the parity
+ * gallery captures. Each entry renders the production composable directly —
+ * the screen reads its data from [com.tt.honeyDue.data.LocalDataManager],
+ * which the capture driver overrides with a [com.tt.honeyDue.testing.FixtureDataManager]
+ * (empty or populated) per variant.
+ *
+ * Scope: the screens users land on. We deliberately skip:
+ *   - dialogs that live inside a host screen (already captured on the host),
+ *   - animation sub-views / decorative components in AnimationTesting/,
+ *   - widget views (Android Glance / iOS WidgetKit — separate surface),
+ *   - shared helper composables listed under `category: shared` in
+ *     docs/ios-parity/screens.json (loaders, error rows, thumbnails — they
+ *     only appear as part of a parent screen).
+ *
+ * Screens that require a construction-time ViewModel (`OnboardingViewModel`,
+ * `PasswordResetViewModel`) instantiate it inline here. The production code
+ * paths start the viewmodel's own `launch { APILayer.xxx() }` on first
+ * composition — those calls fail fast in the hermetic Robolectric
+ * environment, but the composition itself renders the surface from the
+ * injected [com.tt.honeyDue.data.LocalDataManager] before any network
+ * result arrives, which is exactly what we want to compare against iOS.

 /**
- * Roborazzi-driven screenshot regression tests (P8).
+ * Parity-gallery Roborazzi snapshot tests (P2).
  *
- * Runs entirely on the Robolectric unit-test classpath — no emulator
- * required. The goal is to catch accidental UI drift (colour, spacing,
- * typography) on PRs by diffing generated PNGs against a committed
- * golden set.
+ * For every entry in [gallerySurfaces] we capture four variants:
+ *   empty × light,  empty × dark,  populated × light,  populated × dark
  *
- * Matrix: 6 surfaces × 3 themes (Default / Ocean / Midnight) × 2 modes
- * (light / dark) = 36 images. This is a conservative baseline; the full
- * 11-theme matrix would produce 132+ images and is deferred.
+ * Per surface that's 4 PNGs × ~40 surfaces ≈ 160 goldens. Paired with the
+ * iOS swift-snapshot-testing gallery (P3) that captures the same set of
+ * (screen, data, theme) tuples, any visual divergence between the two
+ * platforms surfaces here as a golden diff rather than silently shipping.
  *
- * Implementation notes:
- * - We use the top-level `captureRoboImage(path) { composable }` form
- *   from roborazzi-compose. That helper registers
- *   `RoborazziTransparentActivity` at runtime via Robolectric's shadow
- *   PackageManager, so we don't need `createComposeRule()` /
- *   `ActivityScenarioRule<ComponentActivity>` and therefore avoid the
- *   "Unable to resolve activity for Intent MAIN/LAUNCHER cmp=.../ComponentActivity"
- *   failure that bit the initial scaffolding (RoboMonitoringInstrumentation:102).
- * - Goldens land under `composeApp/build/outputs/roborazzi/`, which the
- *   Roborazzi Gradle plugin picks up for record / verify / compare.
+ * How this differs from the showcase tests that lived here before:
+ *   - Showcases rendered hand-crafted theme-agnostic surfaces; now we
+ *     render the actual production composables (`LoginScreen(…)`, etc.)
+ *     through the fixture-backed [LocalDataManager].
+ *   - Surfaces are declared in [GallerySurfaces.kt] instead of being
+ *     inlined, so adding a new screen is a one-line change.
+ *   - Previously 6 surfaces × 3 themes × 2 modes; now the matrix is
+ *     N surfaces × {empty, populated} × {light, dark} — themes beyond
+ *     the default are intentionally out of scope (theme variation is
+ *     covered by the dedicated theme_selection surface).
  *
- * Workflow:
- * - Initial record: `./gradlew :composeApp:recordRoborazziDebug`
- * - Verify in CI:    `./gradlew :composeApp:verifyRoborazziDebug`
- * - View diffs:      `./gradlew :composeApp:compareRoborazziDebug`
+ * One parameterized test per surface gives granular CI failures — the
+ * report shows `ScreenshotTests[login]`, `ScreenshotTests[tasks]`, etc.
+ * rather than one monolithic failure when any surface drifts.
+ *
+ * Why the goldens land directly under `src/androidUnitTest/roborazzi/`:
+ * Roborazzi resolves `captureRoboImage(filePath = …)` relative to the
+ * Gradle test task's working directory (the module root). Writing to
+ * the same directory where goldens are committed means record and verify
+ * round-trip through one canonical location; we never have to copy
+ * between a transient `build/outputs/roborazzi/` and the committed
+ * fixture directory (which was the source of the pre-existing
+ * "original file was not found" failure).
