Five scripts each hand-rolled colors.toml parsing plus their own alias/fallback cascade, and the tables had drifted: theme-osc grew a divergent color8/color9 chain, tmux and gnome carried private mode detection, and the preview tool duplicated the lot. The differences never mattered for shipped themes but were a standing bug factory for sparse user themes. omarchy-theme-color is now the single resolver. Its cascade is a verbatim port of the canonical theme-set-templates logic (semantic keys, legacy colorN aliases, derived shades, selection/cursor derivation, mode precedence), exposed as --all, --raw, or single-key lookup with fallback. Generated output is byte-identical across all 21 shipped themes on every surface: 17 template files, OSC byte stream, tmux and gsettings command logs, and previews. Sparse legacy themes now resolve the same palette everywhere instead of five slightly different ones. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
