Theme Toggle TDD Checklist

Manual checks (run in a browser):

  • Load the home page with no stored preference; confirm theme matches system.
  • Click the theme toggle once; confirm data-theme changes to dark and icon switches to sun.
  • Click again; confirm data-theme returns to light and icon switches to moon.
  • Focus the theme toggle (mouse click and keyboard tab); confirm no outline ring appears.
  • Verify the toggle button background is transparent and matches the nav background in light/dark.

Automated checks (Playwright):

  • tests/theme-toggle.spec.js verifies the theme attribute, icon class, focus outline, and snapshots.
