- Add explicit viewport meta (device-width) for proper mobile scaling.
- Widen the main container (720 -> 960, 1120 on >=1280px) with fluid
clamp() padding so wide screens are used better.
- Wrap the top nav and allow it to reflow on narrow screens.
- Collapse the key/value grid to a single column and enlarge touch
targets on small screens.
- Keep single-form pages (login/signup/activate) in a readable narrow
column instead of stretching full width.
