Sketch Panel UI Kit — double-framed panels and buttons

Every edge in this kit is slightly wrong on purpose. The outline is sampled along its length and each point nudged, so no line is truly straight and no two corners bend the same way — the thing a ruled rectangle can never do. Shading is cross-hatching rather than a gradient, which is what keeps it reading as drawn rather than as a rounded rectangle with a filter over it.

Two nine-slice panels — a double-framed window frame with 18 px corners and a recessed inset frame with 12 px corners — cover almost every box a menu needs: dialogs, inventory grids, list backgrounds, tooltips and stat panels. Two concentric borders with a gap between them read as carved rather than drawn, which is what separates a crafted interface from a rectangle with a stroke. Both stretch cleanly to any size because the corners never scale and the centre is a flat fill.

On top of the panels sit twelve square button sprites: default, hover, pressed and disabled, each drawn three times — a standard 132×46 bar, a square icon button and a compact button for toolbars and inline actions. The three sizes are separate files rather than one scaled sprite because the drawing is size-dependent: the chamfer computed at 46 px is recomputed at the smaller ones, not shrunk. The pressed state drops its face two pixels and removes the top highlight rather than just darkening, which is what makes a button feel clicked rather than merely recoloured.

Four smaller parts cover what a menu needs between the panels: a tooltip with a pointer tail, a header bar that sits along the top of a panel, a section divider with a centre mark, and a label chip for counts and status tags. None of them are the window panel at another size — a nine-slice already stretches to any size, so a second file at a different width would be filler rather than a component.

Everything ships twice. The SVG sources are the files the kit was drawn in — open them, change the six off-white paper tones or the single ink blue accent, and re-export. The PNG exports are flat, transparent and pre-scaled at 1x, 2x and 4x for engines that want bitmaps, with no premultiplied alpha and no baked-in shadow outside the sprite bounds.
