#59 committed to a full SPA rebuild rather than reskinning Blazor Server pages. Blazor removal is
split into two phases under #91: **(a)** root-flip (SPA becomes `/`) + legacy-route redirects —
DONE, merged via PR #148 (`ErsatzTV/LegacyUiRedirects.cs`, `feat/91-cutover` → main). **(b)** full
Blazor removal — gated on every route having an SPA equivalent; tracked route-by-route in
`docs/blazor-route-parity.md`.
