- * probe.ts — DEBUG-ROUND diagnostic line (phase 3 device-matrix troubleshooting).

- * One category-only instrument line, fixed bottom-left: which WebApp the app
- * sees (version/platform), the character-count of the raw initData (a COUNT,
- * never its content), the last session-gate category, and the location-chain
- * category. No coordinates, no payload, no ids — same law as the Worker's
- * category-only logs (D-14), only surfaced on-screen because a phone
- * webview has no dev-tools access during the device-matrix pass.

- * Rendering uses only machine tokens (letters, digits, separators) — no

- * expected to be REMOVED or reduced at the device-matrix exit.
