What This Changes

A clear, one-paragraph description of what this PR does and why.

Type Of Change

• Typo / broken link / formatting
• Bug fix in an example
• Outdated API reference
• New lesson or section
• Improved example (clearer / shorter / more correct)
• Other (explain below)

Lesson(s) Affected

List the files you touched:

• 01-basics/02-lua-crash-course.md
• ...

Testing

If you changed a code example, confirm:

• I tested the code on a dev server
• The code matches the line-by-line annotation style of the rest of the repo
• All ? placeholders are used in SQL (no string concat)
• Any net event examples include source caching + arg validation
• Doc links resolve

Tone Check

• Plain-English summary at the top of any new lesson
• Every non-trivial Lua line is annotated
• TL;DR section at the bottom
• Next: pointer at the end if it's a numbered lesson
• No filler / marketing speak / unnecessary emoji
• Doc links go to canonical sources (FiveM docs, coxdocs.dev, docs.qbox.re)

Updated Index?

• Updated INDEX.md if I added or renamed files
• N/A - didn't change file structure
