0012. Stylix applies the palette; the palette keeps the hexes

Stylix themes every app it knows, fed FROM my.theme.palette, instead of from a stock base16 scheme.

ContextCopy Anchor Link

Decision 0001 made the palette the single source, but every app had to be wired to it by hand, and a survey of the installed apps on 13/10/2026 found the gap that left: about nine GTK apps (pavucontrol, Bottles, Czkawka, Seahorse, virt-manager, Blueman...) still in stock Adwaita gray, mpv, yazi and LibreWolf with no theme, and Spotify and VS Code pinned to "TokyoNight" by name, so a theme switch would skip them. Stylix (nix-community) has a target for each of those and more.

The obvious use of Stylix is a stock scheme from pkgs.base16-schemes. Measured, that is the argument 0001 already made: the shipped tokyo-night-dark.yaml is not folke's Tokyo Night.

DecisionCopy Anchor Link

Stylix is the APPLIER and palette.nix stays the OWNER. modules/home/desktop/stylix.nix builds stylix.base16Scheme from my.theme.palette, so every Stylix target paints folke's exact hexes and follows my.theme.name like every other consumer. The keys base16 has no slot for (sky, teal, purple, border, shadow) stay with the consumers that read the palette directly: Quickshell, Hyprland, the lock screen, rofi, Kvantum and Zen.

Stylix lives in home-manager only, since my.theme is a home-manager option and its ten consumers read it there. It does not own the fonts (they come from my.fonts.ui, decision 0002), the cursor, the icons or the wallpaper.

ConsequencesCopy Anchor Link

• One more flake input, pinned to the base's release (release-26.05).
• The apps the repo themes by itself stay OFF in Stylix, each with its reason in stylix.nix.
• No color on the TTY console, which is a NixOS-side target. Accepted: autologin skips it.
