Sumi Navigation Kit
===================

15 cel-shaded navigation and input components for dark interfaces — charcoal
wash with seal red accents. SVG plus transparent PNG at 1x, 2x and 4x.

Sumi Navigation Kit is a set of 15 navigation and input components drawn in
the cel-shaded style, where a thick ink outline wraps two flat tones split by
a hard diagonal terminator. It contains active and inactive tabs, a scrollbar
track, thumb and two arrows, a dropdown in closed and open states with its
menu, idle and focused text fields and round close, back, plus and minus
buttons.

Most free UI kits stop at panels and buttons, which means the first settings
screen you build is the moment you start drawing your own art. This is the
rest of it: the parts a menu actually needs before it works.

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 Sumi reading of it: a dark interface on a
charcoal wash palette with seal red accents, built around two concentric
frames, tab-shaped buttons at 120x48, glossy bars divided into 9 segments, and
outlined 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 focused text field widens its outline instead of only changing colour,
because a focus ring that is only a hue disappears in high-contrast mode and
takes keyboard navigation with it. The active tab merges into the surface
below it rather than just brightening, which is what makes it read as
connected.

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 Sumi family, which
means this kit and the Sumi panel kit line up without either being resized. A
good fit for cel-shaded and toon-rendered games.

HOW TO USE

  - Nine-slice the scrollbar track vertically only; the thumb is a separate
    sprite so you can size it to the content ratio without stretching the grip
    lines.
  - The dropdown menu is a separate sprite from the closed control — draw it
    on a layer above everything else, or it clips inside the panel that owns
    it.
  - Use the plus and minus round buttons as a stepper pair at the same size as
    the close button so a settings row keeps one rhythm.
