# Dynamic, interpolated UI text is built with <localizes> message functions
# (this is how the Verse UI APIs accept text -- DefaultText/SetText take a
# `message`, not a `string`). Same pattern our shipping code uses.
CellLabel<localizes>(Row : int, Col : int) : message = "R{Row}C{Col}"
PromptLabel<localizes> : message = "Click a button..."
ClickedLabel<localizes>(Row : int, Col : int) : message = "Clicked R{Row}C{Col}!"

# Holds one generated button plus the grid coordinate it represents, so we can
# both lay it out AND wire its click handler without recomputing positions.

    Button : button_loud

    Col : int

# A device that DYNAMICALLY GENERATES a grid of clickable button widgets in
# Verse (no manual widget placement in the editor) and adds it to a player's
# on-screen UI. Grounded in our shipping grid-of-buttons pattern from
# Scripts/UISystem/minigame_vote_ui.verse (button_loud rows in a stack_box,
# laid out inside a canvas, added via GetPlayerUI[].AddWidget, with each
# button wired to OnClick().Await()).
