Keeps the keyboard selection in the band between the bars; needs `selectionFrame` on rows.

Marks the content top as the `scrollToOrigin` target; apply after the padding.

Publishes the selected row's frame for `scrollFollowsSelection`; only that row measures.

One term against a moment: a spelled duration, or a bare number in the moment's own unit.

Row hover, lit only while the pointer moves; independent of the keyboard selection.

Sized the way Finder does, so a number here matches the one in Get Info.

An `ImageLike`: a string, or `{source, tintColor, mask, fallback}` with a themed `source`.

Base relevance from the strongest matching alias, or nil when none matches.

Empty when the board names no file, so a caller falls through to text or bytes.

A picker's choices: direct children, or grouped in sections that carry the heading.

A feature's commands leave the Commands slice when it is off; `visible` restores them.

Idempotent, so any command can lazily ensure the engine is up.

One channel as a fraction of `scale`; a trailing `%` is always a fraction of the whole.

Called once before composing; the archive carries no directory a category didn't ask for.

The ⌘K rows as the palette's own menu; nil when there are none.

Movement is measured from where the pointer stands now: drift is not a new choice.

Both parameters are injected environment facts, so a harness can drive its own scratch.

A failure with one usable second option; `true` when the user takes it.

Persists or clears the binding and swaps live registration.

Shows the palette, honoring Pop to Root Search. See docs/features/palette.md#state-flow.

One row per file. Batched, so a multi-file copy prunes once rather than once per file.

A floating glass control surface, frosted so it reads brighter than clear glass.

Fragment-tolerant encoding: host results are frequently bare strings, numbers or nil.

The one fold in the launcher: matching, learned-ranking keys and dedup all call it.

The pointer moved, which re-lights the highlight once it has cleared the arming slop.

Focus the app if it isn't frontmost, hide it if it is, launch it if it isn't running.
