/* The "?" beside a word a newcomer may not know (components/Hint.jsx), and
 * the one plain line it opens. Built from shell.css's tokens, in SENDIT's
 * register: the ring is a hairline until it is pressed, then lime, as a
 * chosen preset is; the bubble is a card a shade off the panel with a
 * hairline edge, like the account's panel and a chart face's card.
 *
 * THE BUBBLE IS PLACED BY SCRIPT through --hint-x, --hint-y and --hint-tip,
 * set from an effect (never a style attribute in the markup: style-src
 * 'self'). It is fixed to the viewport, so a strip that scrolls sideways or
 * the ticket's sheet never clips it, and it is not drawn until it is placed
 * (data-side). The ring keeps the line it sits on: its negative margins give
 * the line box no more height than the words beside it, so a label with a
 * hint lines up with one without. */
