 - The stylesheets' keyframes go from 108 to 57: fades, rises, panel slides, exits, spins and pulses all use six shared keyframes (the spec's card, panel and exit among them), and any other keyframe has to be registered with the board that draws it, which a test enforces (3abbbf139).
 - Running dots and icons breathe at the spec's 600ms live duration, and the streaming caret blinks in hard steps as the Think-Exec board draws it instead of fading softly (d8fcc60a0).
 - The empty conversation offers three starting sentences under the hero that fill the composer, and the hero's line reads as the board writes it; the Common settings page ends with a Changed settings card that counts the keys differing from the shipped defaults and lists them (a new read-only /settings-changed endpoint) (cd920a888).
+- The plan-progress, Office preview and new-answer divider settings are on/off switches as the Set-ui board draws them, the Chinese language entry reads 简体中文, and execution rows no longer draw a fold arrow (5552f5fcf). Not changed: the start-mode row has no read-only choice (the kernel's default mode is agent or plan), the light/dark row keeps its scheduled option, and transcript folding and notifications keep their detail buttons because each holds several settings.
