Focus

Menu focus navigation for the cards of BLOCKBUSTER 767. A controller has no pointer, so every menu carries an ordered ring of focusable ids and exactly one of them is lit; this module walks that ring.

• Focus.open(list, prefer) — open a menu: the ids in stick order, and which starts lit.
• Focus.axis(v, dt) — feed the navigate axis; one flick is one step, a held stick repeats.
• Focus.point(id) — a mouse crossing a row or a finger tapping it moves the focus there.
• Focus.id() / Focus.items() — read it.
• Focus.step(delta) / Focus.close() / Focus.release().

Which menu is open lives in modules.state(), so editing this file leaves the card on screen with its rows still walkable.

Fed by game/input/console.inputMap; consumed by game.ui.Screens, which asks it which row to draw lit. Installed from ZeroMind and owned by the presentation slice.
