themes/engine/plymouth/nomarchy.script had `Window.SetBackgroundTopColor(0.101, 0.105, 0.149)` hardcoded — a Tokyo-Night-ish #1a1b26 — and nomarchy.plymouth had a matching `ConsoleLogBackgroundColor=0x1a1b26`. Both were frozen regardless of the active nomarchy.system.theme. Replaced the literals with placeholders (@BG_R@, @BG_G@, @BG_B@, @BG_HEX@) in the source files. themes/engine/plymouth.nix now reads the active palette via `nomarchyLib.getPalette config.nomarchy.system.theme`, converts palette.base00 into three 0.0–1.0 floats (Nix has no floating-point math, so `(byte * 1000) / 255` integer division formatted as `0.XXX`), and `sed`-substitutes both files during installPhase. Smoke-built the derivation against the default summer-night palette: $ cat .../nomarchy.script | grep BackgroundTopColor Window.SetBackgroundTopColor(0.176, 0.207, 0.231); $ cat .../nomarchy.plymouth | grep ConsoleLogBackgroundColor ConsoleLogBackgroundColor=0x2d353b Both match the expected byte→float conversion from base00=2d353b. Closes the "Plymouth theme variants per palette" Next-column item. `nix flake check --no-build` clean.
