Nightcity UI Controls — checkbox, toggle and slider

Controls at 26px with square geometry throughout — there is no curve anywhere in this style, so the round helper draws a chamfered square. The checked state fills with the accent rather than brightening the trace, because a brighter trace reads as focus, not as on.

The set covers the four controls a settings screen actually needs: a checkbox, a radio button, a toggle switch and a slider with a separate knob. Each stateful control ships both states as its own file, at a 26×26 base — the toggle is 52×26 and the slider track is 208 px wide so it can be nine-sliced to any length.

On and off are drawn as different shapes, not different colours. An unchecked box is an empty recess; a checked one is a filled surface with a tick cut into it. That matters because a settings screen is exactly where a player is most likely to be running a colourblind mode, a greyscale shader, or a heavily tinted post-process — and a state you can only read by hue disappears under all three.

The slider ships as a track and a knob rather than a single sprite. Animating a one-piece slider means redrawing it per value; with two pieces you stretch the fill and move the knob, which is what every UI toolkit already expects. The knob carries a centre notch so its rotation and position stay readable at small sizes.

Everything is included as editable SVG and as flat transparent PNG at 1x, 2x and 4x, drawn from the same six midnight blue tones as the rest of the Nightcity family.
