Clean up lesson files by removing useless HTML comment placeholders
from initialCode fields. Users now start with a clean editor instead
of seeing instructional comments they need to delete.
Document learnings for creating effective lessons:
- Clear task instructions with selector and property
- Use codePrefix for context
- Simple, human-friendly values
- Named CSS colors for engagement
- Focused validations
- Semantic HTML in examples
Prevent HTML elements like <details>, <option>, <form> from being
rendered as actual elements in hint messages by properly escaping
them with < > and wrapping in <kbd> tags.
Flexbox and Box Model lessons:
- Use explicit task instructions with selector AND property
- Include selector in codePrefix for better context
- Replace hex colors with named CSS colors (steelblue, coral, etc.)
- Simplify values (2px instead of 0.125rem, 1rem instead of 1.25rem)
- Remove redundant contains validations
- Wrap code examples in <code> tags for proper styling
- Style code elements in task instructions with white alpha background
