refactor: Add strategic comments to organize CSS (Step 5 of 6)

Added inline comments throughout myai.css to:
- Clarify complex CSS selectors (input:not selectors, specificity explanations)
- Explain design patterns (.is-invalid error state pattern)
- Document focus and error states
- Describe layout decisions (sticky result panel, hamburger dropdown)
- Clarify responsive breakpoints and what changes at each
- Explain the relationship between CSS and JS (e.g., .is-open, .is-invalid)

Comments are strategic and concise—added to complex/non-obvious sections
without bloating the file. All CSS rules remain unchanged—purely additive
documentation.

Key sections now have better context:
- Form field selectors and state handling
- Hamburger menu responsive behavior
- Result panel sticky positioning strategy
- Responsive grid layout changes at 900px and 560px
- Cookie banner and loader overlay behavior
