Charcoal Shop UI
================

12 hand-drawn shop and economy widgets for dark interfaces — smoke grey with
ember orange accents. SVG plus transparent PNG at 1x, 2x and 4x.

Charcoal Shop UI is a set of 12 shop and economy widgets drawn in the
hand-drawn style, where every edge is sampled and nudged, so no line is truly
straight. 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 wobble is deterministic rather than random: the same box wobbles the same
way every build, which is what lets it live in version control. Shading is
cross-hatching, because a gradient under a drawn line reads as a filter rather
than as a hand.

Inside that style this is the Charcoal reading of it: a dark interface on a
smoke grey palette with ember orange accents, built around a single bordered
frame, tab-shaped buttons at 160x52, hollow-cored bars divided into 7
segments, and two-tone 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 Charcoal family,
which means this kit and the Charcoal panel kit line up without either being
resized. A good fit for notebook and storybook 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.
