UX-13 P3 review: truthful peak lines, a clock-proof test, Simple stays default
- The peak limit's Why and plan block need a real power request (floor above
  0 W), not a blind or floor-limited guard. An Off battery gets the peak
  block only while it gives power. Why no longer says every battery gives.
- test_batteries_screen pins the fixture clock: unpinned it failed every
  morning. New checks cover the trade and cycle filters, the blind guard and
  an Off battery that A covers alone.
- Settings keeps only a picked view; a link to Installer is not remembered.
- Browser check: badges, unsaved change across views, locked value.

"""UX-13 P3: the headless-browser check of the Batteries screen and Settings,
Simple. Run by `CHECK=1 tools/ux13_screenshots.sh`, like the screenshots.
For every battery-mode fixture (tools/ux13_demo.py) it opens both screens at
phone and desktop width, light and dark, in English and Dutch, and fails on a
page error, a console error or a sideways scroll. Then it clicks the switch
and the mode list on both screens and checks what was posted and what the
cards show after.
python3 ux13_browser_check.py # DEMO_<STATE> = the fixture's URL
