Epic 5 — Fully functional, persisted Settings (theme, accent, thresholds, default template, branding, data)

[xt0n1-t3ch]

A real Settings area where every control does something and persists.

Scope

• Persisted app settings (EF/JSON store) loaded at startup.
• Theme (light/dark/system) + recolorable accent applied app-wide.
• Confidence thresholds that drive the Low/Medium/High tiers.
• Default export template.
• Branding: product name + logo (single owner already started in Brand.cs).
• Data management: reseed demo, clear all data (guarded).

Gate

Change each setting, reload the app, the change persists and visibly takes effect. No dead toggles.

Landed in #39: functional persisted Settings — theme (light/dark/system), recolorable accent (applied app-wide, proven dark+indigo), product-name branding, confidence-tier thresholds, default export template, and data management (reseed/clear). One RuntimeSettings holder; single-row persistence + migration. 25 unit + 12 integration + 3 e2e green.
