ui: confirming an alert dialog should close it

AlertDialogAction was a plain <Button> — only AlertDialogCancel wrapped the
primitive's Close — so confirming ran the action but never dismissed the
dialog. Found in Trippy, where "Clear conversation" cleared the chat and left
the modal sitting on screen; the same component is in every Crema app.

Delete-style dialogs hide it by accident: the row they act on unmounts out from
under the open dialog and takes it with it. Any confirm that leaves its target
on screen (a rewrite, a regenerate, a clear) just gets stuck.

Fixed at the component, so every call site gets it. The action still runs —
Base UI merges its own close handler with the caller's onClick — and async work
carries on behind the closed dialog.

 - **Login** — `app/routes/login.tsx` renders `<LoginForm>` from `@crema/arcadia-auth-ui`. Successful login writes tokens via `persistFromArcadiaLogin()` in `app/lib/session.ts`, which preserves the existing `Session` shape used by `useUser` / `AppShell`.
 - **Realtime** — supported by the lib but not enabled at the provider here; pass `enableRealtime` + `userId` to opt in.

+- `npm run typecheck` **does not crash** — verified 2026-07-14. The old "it crashes, rely on careful reads" note was stale, and it cost us: a route shipped using `Input`/`Textarea` without importing them, which `tsc` reports instantly as TS2304 but nobody was running it. It currently reports ~39 pre-existing errors in `app/` (mostly `TS2322` prop mismatches) and more in sibling libs; treat *new* errors as blocking even while that backlog stands.
+- Every route that renders `<AppShell>` re-exports a shared route-level error boundary (`app/components/route-error.tsx`). Keep that export when adding routes — without it, one crashing panel replaces the entire console with an unstyled stack trace and strands the operator with no nav.
 - Vite "Outdated Optimize Dep" 504s after editing `vite.config.ts` or `tsconfig.json`: stop dev, `rm -rf node_modules/.vite`, restart, hard-reload.
 - After editing a sibling lib's exports, the dev server sometimes needs a manual restart to pick up the new types.

+## Users

+Two audiences share one build, split by JWT capability gating:
+
+- **Platform operators** (`platform_admin`) — Sky AI staff running the whole arcadia-core fleet: provisioning tenants, watching monitoring, rotating secrets, managing SSO, announcements, status page, integrations. Expert, technical, use it daily, usually on desktop.
+- **Tenant admins** (`tenant_admin`) — a customer's administrator managing their own tenant: users, memberships, plan, entitlements, storage, activity. Semi-technical; may visit rarely (only when something needs changing), so rediscoverability matters more than muscle memory.
+
+The job to be done is administrative control of a multi-tenant agentic-cloud platform: "get in, change the thing safely, verify it took effect, get out."
+
+## Product Purpose
+
+Arcadia Admin is the operator/admin UI for arcadia-core (multi-tenant Phoenix backend). It surfaces tenant lifecycle, user/role administration, billing (apps/plan/entitlements), storage, secrets, webhooks, scheduled tasks, SSO, announcements, status page, monitoring, and audit on top of arcadia's `/api/v1` and `/admin/*` endpoints. Success = an operator can onboard a new tenant end-to-end and change any runtime setting without reaching for iex/mix tasks or SSH.
+
+## Brand Personality
+
+Calm, capable, trustworthy. "Premium AI-first glass" (Skyrise theme) but the register is product: the tool should disappear into the task. Confidence through clarity and safe defaults, not decoration.
+
+## Anti-references
+
+- Enterprise admin sprawl (endless nested settings à la old AWS console).
+- Toy dashboards — fake stat tiles, decorative charts with no drill-down.
+- Anything that makes destructive platform actions (delete tenant, rotate secret) feel casual.
+
+## Design Principles
+
+1. **Safe by construction** — destructive/irreversible actions are explicit, confirmed, and auditable; errors name the fix.
+2. **One contract, everywhere** — capability map drives nav and guards; `data-action` ids on every interactive element (AI/script drivable).
+3. **Verify what you changed** — every mutation reflects visible state (toast + updated row + audit trail), never silent success.
+4. **Recognition over recall** — a tenant admin who shows up quarterly should find everything from the sidebar without training.
+5. **Density where experts live** — tables and panels can be dense, but each screen has one clear primary action.
+
+## Accessibility & Inclusion
+
+WCAG AA floor (4.5:1 body text), full keyboard operability, visible focus, labeled icons, `prefers-reduced-motion` honored. Desktop-first but mobile shell must remain usable (operators respond to incidents from phones).

 - Writes are auditable. Suggest the user double-check tenant slug and impact before suspend/deactivate. Deactivate is harsher than suspend — only use when clearly intended.
 - The operator can impersonate tenant users for debugging (POST /api/v1/admin/impersonate/:user_id) — surface this when they ask "why can't user X log in".
 - Quotas / rate cards / billing config errors usually surface as 402/403 from /api/v1 endpoints — diagnose by checking the tenant's billing-config and api-metering quotas.

 When the user asks something that maps to a tool, call it. When they ask about a concept, explain it from this primer in plain language. Write tools (suspend_tenant, activate_tenant) prompt the operator with an inline confirm card before they actually run — you do not need to ask in prose first; just call the tool and the user will see the confirmation UI. If the user denies a write, do not retry it; ask what they'd like to do differently.
