Scanline Panel UI Kit — single-framed panels and buttons
========================================================

Single-framed nine-slice deep scan window panels, inset list frames and four
chamfered button states, as SVG plus transparent PNG at 1x, 2x and 4x.

Scanner panels rather than a projection: deeper blues, an ember trace and a
thin line that reads as light rather than paint. The halo does the work a
heavy outline would do in another style.

Two nine-slice panels — a single-framed window frame with 0 px corners and a
recessed inset frame with 0 px corners — cover almost every box a menu needs:
dialogs, inventory grids, list backgrounds, tooltips and stat panels. A single
continuous border keeps the panel quiet enough to sit behind dense text. Both
stretch cleanly to any size because the corners never scale and the centre is
a flat fill.

On top of the panels sit four chamfered button states: default, hover, pressed
and disabled. They are drawn on the same 120×34 base with 0 px corners, so you
can swap the texture on a single button widget and get the whole interaction
loop without moving a rectangle. 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.

Everything ships twice. The SVG sources are the files the kit was drawn in —
open them, change the six ocean black tones or the single ember orange 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.

HOW TO USE

  - In Unity, import the PNGs, set Texture Type to Sprite (2D and UI), and set
    the border to 0, 0, 0, 0 for the window panel and 0, 0, 0, 0 for the
    buttons; then set Image Type to Sliced on the UI component.
  - In Godot 4, use a NinePatchRect and set the patch margins to the same
    numbers, or drop the SVG straight in and let Godot rasterise it at the
    scale you set in the import options.
  - In Unreal, import as a Texture2D, create a Slate Brush with Draw As set to
    Box, and enter the margin as a fraction of the texture size — for the 100
    px panel and for the 120 px button.
  - For crisp results at non-integer UI scales, use the 2x or 4x PNG rather
    than upscaling the 1x, or point your engine at the SVG source and let it
    rasterise at the final size.
