New plugin:hyprchrome:glow_size (px, 0 = off) and glow_strength (0-1)
bleed the border's own gradient inward past the window edge, over the
window's own pixels. Off by default, so existing setups are unchanged.
Drawn into the hole the ring's even-odd fill already leaves behind, from
overlapping layers - one per px of depth - each covering the window edge
inward to a progressively greater depth. Overlapping rather than abutting
disjoint bands avoids an antialiasing seam at every shared edge; the cost
is that a layer composites over every deeper one, so its alpha is solved
outermost-inward from the target profile rather than being it.
That profile is strength * (1 - d/glow)^2.2: steep off the window edge,
easing into a tail that reaches zero tangentially so there's no ring
where it stops.
Corner handling, in order of how much it mattered:
- Each layer's outer edge is the ring's inner boundary verbatim, chamfer
vertices and all. Anything else detaches the glow from the frame and
opens a sliver of unpainted window at each corner.
- Each layer's inner edge - which is what the falloff's contours actually
follow - is filleted in proportion to its own depth, so the glow reads
as chamfered where it meets the frame and rounder as it fades inward.
- Those inner edges also shrink their chamfer by (2-sqrt2) per px of
inset. Insetting a chamfered rect while holding the chamfer constant
moves the 45-degree face in by d*sqrt(2) rather than d, which had the
glow running ~41% deeper at every corner than along the sides.

The old workflow grepped CMakeLists.txt for the first "VERSION X.Y" match,
which was cmake_minimum_required's own version rather than the project's,
mangling it to 3.27.0.0 on the first real bump. PLUGIN_VERSION in .env is
now the single source of truth for both CMakeLists.txt and flake.nix, and
the workflow's bump/commit steps only ever touch that one file.

The session loads its own copy of the plugin from the Hyprland config, a
separate dlopen with its own decorations - so iterating with a dev build on
top of it drew two frames on every window.
Grep the path back out of $XDG_CONFIG_HOME/hypr rather than hardcoding it:
a home-manager-installed copy lives at a /nix/store path that changes on
every rebuild. -R, since those config files are symlinks into the store.
hyprctl plugin list reports no path, so the config is the only place to
read it from.

The frame collapsed Hyprland's border gradient to m_colors.front(), so a
gradient col.active_border showed up as a single flat color.
Snapshot the gradient (stops + angle) into a new header-only ChromeGradient
and fill the cairo path with a linear gradient built from it:
- AxisFor() reproduces the border shader's quadrant-folding progress
function (y*sin(a) + x*(1-sin(a)), not a true rotation) as a cairo axis,
so the frame's sweep stays in step with the window border it wraps.
Checked against a port of the shader across all 360 degrees: cardinal
angles exact, worst case 0.003 of the sweep (the shader folds on literal
1.57/3.14/4.71 where this uses pi).
- SampleAt() interpolates in OkLab, where the shader interpolates, with
each segment subdivided into sampled cairo stops so cairo's own sRGB lerp
tracks that curve.
active_color/inactive_color become gradient config values, taking the same
syntax as general:col.active_border. Single-color configs are unaffected.
The cross-focus fade (m_realBorderColorPrevious + fade progress, lerped
between two gradients in-shader) is still not reproduced.
