Summary

• Keep the phone home screen on a phone held sideways: isMobileLayout(true) also matches iPhone|iPod|Android.*Mobile, so Android tablets keep the desktop layout.
• Scale the phone layout by height as well as width (BASE_VH), and stop scaling above the widest phone (430) so wider layouts get more cells instead of larger ones.
• Size the Dock box from its icons when the grid caps them (dockFit), keeping the icon-to-Dock ratio of a full-size phone; the search pill follows the Dock height.
• Count rows from the column width on layouts wider than a phone with labels hidden, so cells stay square and two icon rows match a small widget.
• Settings keeps its sidebar on short landscape windows (max-height:500px) and on screens at least 600 wide with a window at least 600 wide; the sidebar is 200px below 769. The preload script mirrors the rule.
• Set -webkit-text-size-adjust:100% in widget-theme.js, so iOS Safari no longer enlarges widget text in landscape.

Testing
All green, including e2e on Chromium and WebKit. Added tests for the sideways rules, height scaling, square cells, Dock sizing and widget text sizing.
