Rename the palette keys to the canonical background/foreground names the resolver actually reads. The short bg/fg spellings were never aliased, so every derived key was silently falling back. Fill in the orange and brown slots too. Lupine is a deliberately cool, near-monochrome blue palette, so both stay in family rather than introducing warm hues the theme never had. Drop neovim.lua and vscode.json. They pinned third-party extensions that had to be installed separately; the generated templates cover both from colors.toml alone.
