The bar repainted itself whole every second. It now compares each field against what it last painted, adds seconds and a memory percentage, and keys the cache on gui.getRotation() and ui.themeName so rotation and theme changes still repaint it. Invalidation lives entirely in Lua; the firmware's push flag and gfx/statusbar.h are gone. Bindings follow getName/setName/isName, persisted preferences move from sys to a settings table, and gui.setRotation takes degrees like settings does. A bar that dies mid-run now keeps its rows reserved rather than silently resizing the running app.
