 * (hub, three landings, auth, app). public/admin.html loads only admin.css —

 *   - the gap tightens to 8 px below 560 px;
 *   - below 420 px the title was invisible already and only held space as a
 *     flex spacer; the logo does that job now, and an auto margin keeps the
 *     controls flush right, which is what the spacer was for.
 *
 * The ⌘K palette button only has to go below 375 px. Measured with the widest
 * corpus badge („Schilling", 77 px): at 375 px the row still ends at 367 px of
 * 375 with the button in place, at 360 px it overruns by 2 px. So 375 px — the
