Explorer rows become the app's tree-row cell — 34px, radius 8, inset by
the scroll padding, 22px indent step, and the session-row mount fade —
and git rows get the same cell plus the proper selected fill
(interactive-bg-active). Icon buttons switch to the app's 28px circle
pattern (ui-workspace), headers settle at the 36px section rhythm, and
keyboard focus gets a visible ring everywhere per the styling policy,
with a prefers-reduced-motion block turning off the slides and fades.
