 * The topbar is brand + summary + five buttons on one row. On a 390 px phone
 * the brand and buttons take ~320 px of it, which leaves ~70 px for a string
 * that wants ~210 ("Verkko 3/4 · 2 seurainta · 5 min sitten"), so it wrapped
 * to three lines and the topbar grew to twice its height -- straight out of
 * the map, which is the one thing the screen is for.
 *
 * Giving the summary its own full-width row costs 20 px and saves 40, and it
 * is deterministic: one line whatever the language does to the wording.
 * Finnish is the longer of the two and is what this has to survive.
