// title sheen — chrome

// Hand-written, unlike contrib/shaders: those are generated from
// contrib/shadertoy.html, and the toy previews a pane's *contents*. A frame is
// a different rect and the toy has no frame to show.
//
// Drop this into ~/.config/slosh/config.kdl (a running session picks it up
// when you save), or point $SLOSH_CONFIG at this file. To hang it off a pane
// state instead of every pane, put the same pass inside one:
//
//     states { bell { ... } }
//
// The top rule only, where the title sits: a sheen crossing it left to right.
// `y == 0` picks the rule out; the rest of the frame is left alone.
