Coding Practices

Single responsibility: Each source file should have a clear, focused scope/purpose
Split large files: Break files when they become large or handle too many concerns
Type separation: Always separate types and interfaces into types.ts or types/*.ts
Constants extraction: Move constants to a dedicated constants.ts file

Prefer isomorphic code: Write runtime-agnostic code that works in Node, browser, and workers whenever possible
Clear runtime indicators: When code is environment-specific, add a comment at the top of the file:

// @env node
// @env browser
