Deco TypeScript Fixes

This skill provides strategies for systematically fixing TypeScript errors in deco.cx storefronts. It's especially useful after:

• Migrating from forked apps to official deco-cx/apps
• Updating @deco/deco or @deco/dev versions
• Adding stricter TypeScript settings

When to Use This Skill

• User asks to "fix all type errors" or "make deno check pass"
• After a migration that introduces many TypeScript errors
• When enabling stricter type checking in a deco project
