-- Code formatting configuration
-- Sets up formatters for SQL and Mojo languages
-- Biome/Prettier for JS/TS handled by LazyVim extras:
--   lazyvim.plugins.extras.lang.typescript.biome
--   lazyvim.plugins.extras.formatting.prettier
-- This config also makes prettier yield to biome when a biome config is present,
-- so a global ~/.prettierrc doesn't clobber biome-formatted output.
