Configuration

Indentier is cosmiconfig-powered. It auto-discovers config from:

• package.json → "indentier" field
• .indentierrc.json / .indentierrc.yaml / .indentierrc.yml
• .indentierrc.js / .indentierrc.cjs / .indentierrc.mjs
• .indentierrc.ts / .indentierrc.cts / .indentierrc.mts
• indentier.config.{js,cjs,mjs,ts,cts,mts}
