/*
 * /watchlist (watchlists/show, _map, _table): every company a reader
 * follows, as the strip's heat tiles by sector or as tables that sort. The
 * heading and the serif standfirst, a hairline-ruled row of choices — view,
 * grouping, the export — then one `.card` per group.
 *
 * In the table view a group folds on its own <details>; its summary is the
 * card's header row, so the fold reads as the section heading it is, with a
 * chevron at the far end that turns when it is shut. "All together" draws
 * one table and no fold. The tables are one form: a checkbox beside each
 * ticker, a "select all" over each group once the `selection` controller is
 * there, and a bar that stays at the foot of the window while the tables
 * scroll past, with the count and the one button that unfollows.
