 * The stop editor.
 *
 * Designed against one sentence: "done when a stop can be created standing in a park with one hand."
 * Everything here follows from that and from the sunlight/touch requirements:
 *
 *   - Primary actions sit at the BOTTOM, inside the thumb's arc. A save button at the top of a phone
 *     screen requires a second hand or a grip change, and the organizer has a child in the other one.
 *   - 48px minimum on anything tappable, above the stated 44px floor, because the target user is
 *     walking.
 *   - Ink on paper contrast, no thin grey type. Read in direct sun.
 *   - The two secret fields are marked in the layout itself, not only in words. Publishing a hiding
 *     note to families is the failure that ends the hunt.
 */

/*
 * `[hidden]` must actually hide.
 *
 * The attribute is honoured by a user-agent rule of the very lowest specificity, so ANY class rule
 * that sets `display` beats it. Three things here are laid out with flex and start hidden — the
 * sheet, the passcode strip and the map-style chips — and without this the "hidden" sheet sat over
 * the whole screen at full size, invisible to a reader of the markup and fatal in practice: every
 * tap on the page beneath it was swallowed, so the editor could not be used at all.
 *
 * Found by driving the real page in a real browser. No unit test and no amount of reading the HTML
 * would have caught it, because in both of those the attribute is simply "set".
