themes/{catppuccin,lumon,nord,retro-82}/style.css fully replaced the
default style.css (no @import) but defined only 2–14 lines — just
@define-color declarations and, for nord, a minimal window#waybar block.
The default style ships ~110 lines covering #workspaces, #tray, #cpu,
#custom-nomarchy's Nomarchy-font override, margins/padding, the indicator
.active states, etc. So picking any of those four palettes produced a
waybar with zero structural styling.
The default style at features/desktop/waybar/config/style.css already
@imports ../nomarchy/current/theme/waybar.css — which themes/engine/
files.nix:30-34 generates with @background/@foreground/@accent from the
active palette. So removing the broken overrides restores per-palette
colors via the default-style path. summer-day and summer-night are kept
because their 100+-line style.css files are intentional, self-contained
visual redesigns (the case the themes/engine/loader.nix:76-79 comment
explicitly carves out for "themes that need significantly different
styling").
