/*
 * DevTools panel: a paper sheet laid on the tool.
 *
 * Tokens, the severity language and the theme decision live in
 * ../shared/kinpaku.css. The short version, because it shapes every rule
 * below: one light theme in both DevTools themes; gold is the mark, the
 * tag and the lit dot on a control; patina carries any colored text;
 * selectors and counts are mono, as they are in the agent.
 *
 * How a finding reads here:
 *   AI tells   gold. A lit gold dot on the section, the count as the
 *              detector's tag, the section name in ink.
 *   Quality    patina. A patina dot, a quiet gray count, a muted name.
 *   Selector   patina-deep mono in both sections: it is the one piece of
 *              colored text, and patina is the color that may carry text.
 *
 * Controls are paper hardware: a recessed track, a raised cap that stands
 * a millimetre proud, and a gold dot that lights when the cap is the one
 * selected.
