The sidebar collapses to icons *below* 900, so the main panel is 843px at 899 and 700px at 900: the narrowest content area any desktop width produces is at the top of the Compact band, not at the enforced floor. A viewport list that stopped at "the minimum" was missing its own worst case. MinWidth's comment loses both reasons it used to give, because neither mechanism can happen any more — the subtitle is display:none from 899 down, and the sidebar host is overflow-y:auto (at 600x460 its scrollHeight is 434 against a 332px client, and Settings is reachable after scrolling). The value does not change: 800x600 is where desktop chrome stops being comfortable, not where the app breaks, and below 600 the phone layout takes over. A floor defended by two expired mechanisms is a number nobody can argue with, which is worse than either answer. Closes #24
