The gate `tengu_static_title_under_mux` defaults to true, so this is live for everyone in a multiplexer unless remote config turns it off.\n\n**Details**\n\n- Detection uses the session's multiplexer info or the `TMUX`, `STY` and `ZELLIJ` environment variables.\n- With the condition met, the spinner glyph is dropped from the title and no frame timer runs.\n- Outside a multiplexer, nothing changes.\n\n**Evidence**\n\n`tengu_static_title_under_mux`\n\n- Flag `tengu_static_title_under_mux`: Not enough to say (read for one account on one subscription tier against v2.1.236; this account: no value returned, anonymous baseline: no value returned, compiled default: on)\n- Area: Terminal UI\n- Tier: You'll notice\n- Useful: 3\/5\n- Signal: 2\/5"}
