Inkwell Shop UI
===============

12 cel-shaded shop and economy widgets for light interfaces — flat poster with
signal red accents. SVG plus transparent PNG at 1x, 2x and 4x.

Inkwell Shop UI is a set of 12 shop and economy widgets drawn in the
cel-shaded style, where a thick ink outline wraps two flat tones split by a
hard diagonal terminator. 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 shadow is a single hard-edged shape with no falloff — the defining
property of cel shading, and the thing a gradient can never imitate. The
outline uses the darkest tone in the palette rather than the border tone, or
it reads as a thick grey frame instead of ink.

Inside that style this is the Inkwell reading of it: a light interface on a
flat poster palette with signal red accents, built around a single bordered
frame, square-cornered buttons at 152x52, banded bars divided into 5 segments,
and solid icons on a 24px 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 Inkwell family,
which means this kit and the Inkwell panel kit line up without either being
resized. A good fit for cel-shaded and toon-rendered games.

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.
