+
+Two fixes from spec 011's live acceptance walk, in this spec's `frontend/`
+territory. `lib/api.ts`: Encore decodes DELETE payloads from the query
+string, so `apiSend` now encodes DELETE bodies as query parameters (tenant
+delete, fleet remove, and operator membership revoke were all unusable
+from the SPA before this). `routes/dashboard.tsx` plus a `page-actions`
+rule in `styles.css`: the tenant-less install URL (spec 011 §5.6) gains
+its UI entry, with the empty state leading on "Install the GitHub App"
+and the page header offering "Install into a new org"; GitHub's own
+install picker does the org selection, so no in-app org chooser exists.
