/*
 * 猜心 — the page's own rules.
 *
 * The shell comes from app.css (the column, topbar, brand mark, buttons, status
 * line, the panel and its head/foot), which this page links even though it runs
 * none of the scatter engine — the family's shell in one place, and the rules
 * that match nothing here simply match nothing. What is left for this file is
 * the shape none of the other tools has: a stack of question cards whose answer
 * chips are marked up *after* they have been answered.
 *
 * [Why the checkmark marks are classes on the option, not a separate list] The
 * reveal belongs where the question is. A person who has just been told 「猜中 5
 * 题」 wants to look at the three they got wrong, and a second list of eight rows
 * would be the same eight facts in a place they have to scroll to. So the panel
 * below carries the misses in words, and the cards carry the marks in place.
 *
 * Three rules here are copies of rules in other tools' sheets — `.paste`, the
 * link textarea, and `.verdict` — because those sheets are per-tool by
 * construction and there is no sheet they could have come from. The shell is the
 * thing this family shares; a per-tool sheet borrowing another per-tool sheet
 * would be the coupling app.css exists to remove.
