Build one project-aware Lab page over the LabDoc protocol. It must render narrative Markdown/math, pure-render cells such as GPCR, executable WASM cells, diagnostics, artifacts, provenance, and live run events. Reuse the existing Fossil-authenticated CGI, worker, and SSE machinery rather than introducing a separate web stack.

Acceptance: - Read-only viewing works without starting a runner. - Run controls are capability-gated and CSRF-protected. - The page distinguishes source, derived rendering, ephemeral run output, and blessed output. - Live events survive reconnect and terminal state is reconciled from the run ledger. - The route remains project-aware and CSP-safe. - A static/no-JavaScript representation remains useful.
