Redline Shop UI
===============

12 cyberpunk shop and economy widgets for dark interfaces — blood black with
warning amber accents. SVG plus transparent PNG at 1x, 2x and 4x.

Redline Shop UI is a set of 12 shop and economy widgets drawn in the cyberpunk
style, where every frame has its own asymmetric outline — a notch on one
corner, a rail down one edge. It contains four purchase row states, an active
and an idle category tab, a wallet strip, a quantity stepper, a purchase
confirm strip and three countable stock indicators.

A shop screen has one job an inventory screen never has: it must tell the
player what they cannot afford before they press the button. Most free sets
solve that by turning the price red, which fails for the players who cannot
read that red and fails again on a greyscale screenshot. It also collides with
the health colour every other part of the interface already uses.

The silhouette is composed rather than scaled: each of the four corners and
four edges takes its own treatment, so no two frames in the set share an
outline. The neon glow is a stack of strokes at falling opacity, not a blur
filter — a filter is applied differently by some SVG rasterisers and turns the
halo into a smear at 4x.

Inside that style this is the Redline reading of it: a dark interface on a
blood black palette with warning amber accents, built around a single bordered
frame, chamfered buttons at 140x36, hollow-cored bars divided into 10
segments, and two-tone icons on a 32px grid. Those measurements are why two
families can share an art style without being interchangeable: the style
decides how an edge is drawn, the numbers decide what the interface is for.

The four row states are told apart by structure rather than by colour. An
affordable row carries a solid strip down its left edge, an unaffordable one
carries a dashed strip and a bar struck across its price field, and an owned
one caps the price field shut and marks its top-right corner. That means the
state survives a tint, a colourblind filter and a screenshot with the
saturation pulled out. The stock indicator is countable for the same reason:
five dots, one dot and none read as full, low and sold out without a single
word or hue.

Every sprite ships as an editable SVG and as transparent PNG at 1x, 2x and 4x,
so you can drop the PNGs straight into an engine or open the vector and change
a colour. Built to the same measurements as the rest of the Redline family,
which means this kit and the Redline panel kit line up without either being
resized. A good fit for cyberpunk, sci-fi and near-future interfaces.

HOW TO USE

  - Nine-slice the rows on their straight left and right regions; the price
    field on the right is a fixed width so a long item name never pushes it
    out of alignment.
  - Use the dashed strip and the struck price for unaffordable rather than a
    red tint. Both are pattern rather than hue, so they hold up in greyscale.
  - Stack the stock dots in the same slot every row uses, and drive them by
    count rather than by colour.
  - The confirm strip and the quantity stepper share a height, so a shop can
    put them on the same line without either being resized.
