+## [Unreleased]
+
+### Changed
+- **Mobile web terminal input**: mobile clients (`pointer: coarse`) no longer enforce an implicit read-only mode in the web UI. Keystrokes from phones/tablets now flow to the tmux session like any other client. To preserve the previous behavior, start the web server with `agent-deck web --read-only` — the server-side flag now owns read-only enforcement for all devices.

 ## [1.5.4] - 2026-04-16
 
 ### Added
