-#version 450
-// pardes's Shadertoy prefix (docs/render-pipeline.md §6), put before every
-// post pass: a bundled one in shaders/post/ at build time, a user's file at
-// run time. The uniform names, types and std140 order are ghostty 1.3.2's
-// (src/renderer/shaders/shadertoy_prefix.glsl), so a shader written for
-// ghostty runs here; only the bindings are SDL GPU's (a fragment shader's
-// textures in set 2, its uniform blocks in set 3). Y is down everywhere, as
-// on ghostty's Metal renderer: fragCoord, iChannel0's uv and the cursor
-// rectangles share one top-left space, and iCurrentCursor is (left x,
-// BOTTOM-edge y, width, height) in framebuffer pixels.

-// pass's strength, 1 to 3 (`Crt 3`), and 0 for a user's file; pardesScale
-// is the display's density (2 on a 2x screen), for a pass whose pattern is
-// in logical pixels. iResolution, fragCoord and iMouse stay in the display's
-// pixels, as ghostty's do. pardesCap is the most a bundled pass may do on
-// this theme and still leave its text, and its selection's, at their own
-// contrast or 4.5 (docs/effects.md); pardesSpare holds pardesSpareCount
-// rectangles (x0, y0, x1, y1 in fragCoord's pixels) a bundled pass leaves
-// alone: every tag, grip and notice, and the cursor, so no pass ever touches
-// a focus indicator.
