Provide a reduced-motion mode for the Codex CLI TUI.

CLI

What feature would you like to see?

Issue:

The TUI currently animates status text (e.g., "Waiting for background terminal…") using a fast-paced shimmering/sweeping text effect rather than a static label. For some users, this kind of fast continuous moving-text animation is cognitively taxing to look at, especially during long-running waits — it draws visual attention involuntarily and makes the status line harder to read rather than easier. This is a similar concern to why many terminal tools and accessibility guidelines avoid persistent motion effects on readable text.

Proposal:

Add a reduced-motion mode that disables the shimmer/text-sweep effect on status text, falling back to either:

a static status label, or
pulsing status dot

Start by locating the Codex CLI TUI code that renders animated status text such as "Waiting for background terminal…" and trace how its animation is selected. Implement a reduced-motion option that replaces the shimmer or sweep with a static label or pulsing dot, then run the relevant TUI tests and verify that status text no longer continuously moves in that mode.
