- AppearanceSettings derives Default instead of carrying a manual impl
that's identical to the derived one.
- topbar::render_lock_or_search collapses the duplicated Search arms
into a single fallback so clippy stops flagging identical blocks.
- command_overlay row helpers bundle id/title/hint/keys into a small
CommandRowContent struct so render_row, render_row_with_glyph, and
render_row_inner stay under the 7-arg threshold without losing any
call-site clarity.
