Hologrid Backdrops
==================

7 hologram background and overlay pieces for dark interfaces — abyss navy with
signal amber accents. SVG plus transparent PNG at 1x, 2x and 4x.

Hologrid Backdrops is a set of 7 background and overlay pieces drawn in the
hologram style, where a thin trace carries a wide halo, and most of the frame
is empty space. It contains a full-screen menu backdrop, a seamless pattern
tile, a modal dimming overlay, a title banner, a section divider and a loading
bar track and fill.

This is the piece most free UI kits leave out entirely. A kit that gives you
panels and buttons but nothing to put them on stops being useful at the first
screen you build, and the backdrop is the one thing you cannot fake with a
flat colour without the whole menu looking unfinished.

The halo is a stack of strokes at falling opacity rather than a blur filter —
a filter is applied differently by some SVG rasterisers and smears at 4x. The
trace is deliberately thin: a projected interface reads as light, and a heavy
line reads as paint.

Inside that style this is the Hologrid reading of it: a dark interface on a
abyss navy palette with signal amber accents, built around a single bordered
frame, square-cornered buttons at 132x38, tick-marked bars divided into 20
segments, and outlined 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 backdrop is where an art style has the most room to show itself, so it is
drawn differently in each: dithered bands, a triangulated mosaic, hatched
paper, an isometric grid, a hard-edged horizon. It ships at 640x360 and
exports to 2560x1440 at 4x, which covers 1080p with the aspect held, so it
stretches to any resolution with a single cover fit. The pattern tile closes
every motif inside its own bounds, so tiling shows no seam.

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 Hologrid family,
which means this kit and the Hologrid panel kit line up without either being
resized. A good fit for sci-fi projections, scanners and near-future overlays.

HOW TO USE

  - Use the backdrop with a cover fit rather than stretch — the 16:9 aspect is
    deliberate and distorting it is visible immediately on a gradient.
  - Tile the pattern behind lists and inventory grids at 1x for a fine texture
    or 2x for a coarse one; it is seamless in both directions.
  - Draw the scrim between the game and a modal at full screen. It is the
    style palette rather than flat black, so it does not grey out a coloured
    game.
