; For full project documentation, architecture, and conventions see AGENTS.md in the repository root.
;
; Quick rules:
; - ESM TypeScript project (@xhubio/nanook-table), Node >= 22
; - No semicolons (Prettier removes them)
; - Single quotes, no trailing commas
; - PascalCase classes, camelCase functions/properties
; - Max 3 function parameters
; - No namespace imports — import only what you need
; - Use .js extension in relative ESM imports
; - xlsx: use default import (import XLSX from 'xlsx'), NOT namespace import
; - Tests: Vitest, in tests/ directory, pattern *.test.ts
; - Build: npm run build | Test: npm test | Lint: npm run lint
