gramps 71d0e87cac feat(blur): a privacy blur layer for the Live scene — boxes and circles over the desktop
Creator request 2026-11-01: a layer that hides part of the desktop from viewers. Box or circle,
drag/resize like any layer, one strength slider, several allowed.

**Z-order is policy, not preference.** `AddSource` inserts a blur directly above the background
and therefore below the brand logo, and `OnSceneElementsReordered` pushes any blur that ends up
above the brand back down. Nothing else in the app can move it into the brand's way.

**Overlap = the strongest single blur, never a stack.** `SceneCompositor.ApplyBlurLayers` collects
every visible blur the first time one is reached in the z-order, sorts them strongest-first, and
shares one coverage map: a pixel already covered by a stronger blur is skipped. Blurring
back-to-front would have produced something stronger than any slider setting allows, which is
exactly what was ruled out.

**One blur curve, shared with the webcam.** `RegionBlur` carries the constants the webcam blur
already used — downscale 4, radius 1–6 downscaled px, `RadiusFor(strength)` — and
`BackgroundEffectProcessor` now delegates to it instead of holding its own copy. The layer's
slider is the same 0–1 scale with the same 0.5 default, so "half strength" means the same blur in
both features. Cost is proportional to the blur's own rect, not the frame.

**Live scene only**, enforced in `AddSource` as well as the (+) menu (`CanAddBlur`), so a stale
menu item or a scripted call cannot plant one on BRB. `ElementKind.Dynamic`, so it is never baked
into the static base and every render path gets it — pump, preview, thumbnails, scene dump.

Persistence: `Source.BlurAmount` column + migration; shape rides the existing `ClipShape`.
Properties panel: Box | Circle plus the strength slider, gated on `IsBlurSelected`.

4 tests: outside the mask is byte-identical, inside loses its hard edges, a circle leaves its
box corners alone, and two identical stacked blurs equal one (the coverage map). Release builds
at 0 warnings.

Monetization policy locked + dev pause recorded (docs changeset, 2026-08-14): the one paid line becomes an annual subscription — early access $49.99/yr → $99/yr list at GA, grandfather-while-subscribed with lapse → list on renewal (no escalation matrix); free tier unchanged (branding flash is the free tier's billboard + no Alerts, which is the one paid feature); billing NOT locked to itch.io (hunted fact: itch.io has no native subscription billing — candidates Gumroad, whose native affiliate program is the tiebreaker, and Lemon Squeezy); support = in-app bug-report → git issues with a when-I-get-around-to-it cadence + emergency patches. ai.md Monetization section rewritten + stale paid-unlock seams fixed (L115 subscription-entitlement wording, the About hub's tabled billing PremiumUrl seam); TASKS.md gains TASK 23 (Monetization — billing provider decision, unlock mechanism with lapse→flash-returns enforcement, in-app bug-report loop, Unlock Premium seam lighting, Alerts gating, and line-item pointers for the early-access strategy, affiliate/ads phase 2, and the channel revival); HANDOFF.md records the decisions + the development pause (resume streaming = pair-programming dev streams via OBS + The Division 2 under the gramps/GOAT persona, 67 and gaming since 1981, 3D-printing content retired; dogfood switch to ytLlive once TASK 5 lands; resume point = TASK 5). Stale itch.io assertions corrected across comments and indexes (MainViewModel.cs PremiumUrl/IsPremium seams, MainWindow.xaml tooltip, AboutHubTests comment, ViewModels/index.md, TASK 9 out-of-scope note). Build 0 warnings, 196 tests passing
