Command palette — accessibility

Keyboard

⌘K / Ctrl+K opens the palette from anywhere; Esc closes it.
↑ / ↓ move through a flat index across all Item lists in the left column — sections do not trap the cursor, so one hold of the arrow key crosses from Lidé into Firmy.
↵ opens the row under the cursor. ⌘↵ hands the query to the assistant (the same path as clicking the footer).
The cursor sits on the first row from the moment the palette opens, so ↵ always does something.
A prefix character (@ # > ?) is consumed into the .gsp-pre token; Backspace on an empty field removes the token and returns to the full scope.
Locked rows are not focusable and carry no click — they are found and marked, never opened.
On mobile the detail is a second step: opening a row replaces the list, and .gsp-back returns to it.

The shell is role="dialog" with aria-modal="true" and aria-label="Hledat".
The input is role="combobox" with aria-expanded, aria-haspopup="listbox" and aria-activedescendant pointing at the active row.
Each section's list is role="listbox" with ariaLabel set to the section title; rows are role="option".
The active row is announced through aria-activedescendant — focus itself never leaves the input, so typing continues to work while the cursor walks the list.
The .acrm-kbd shortcut chips are aria-hidden: they are a visual hint, and the accessible name is carried by the row and by the button label.

Focus enters the input on open and stays there for the whole session of the overlay.
On close, focus returns to what invoked the palette.
The footer is a real <button> spanning the full width of the footer row, so it is reachable by Tab as well as by ⌘↵.

Row text --ink-900 on --surface-100; secondary and tertiary slots step down through --fg-secondary and --fg-muted, all on the same 13px type — the hierarchy is carried by colour, never by size or weight.
The status strip uses --warning-ink on --warning-subtle; a failed section label uses --critical-ink.
The match highlight is --accent-ink on --accent-tint, the same pair the meeting transcript search uses.
The active row is --selected, which is a background change only — the row keeps its text colours.

The cursor index is flat across lists, so a screen reader hears section boundaries only through the listbox labels, not through a position announcement.
The status strip is not a live region: it is rendered with the results rather than announced when the engine state changes.
The masked sub-label of a locked row is the literal ***, written by the client — the server never sends the hidden values, so there is nothing more descriptive to announce.
