 * THE SHARED PARTS: the row, the list, the states, the notice, the Details disclosure, the small
 * controls and the field (`row.js`, `list.js`, `states.js`, `notice.js`, `disclosure.js`, `controls.js`;
 * a field is three class names on a page's own label, caption and control). They began
 * as Feed's and every page draws with them now, so their look is declared here, once, and holds
 * wherever a part stands: no rule below needs a page around it.
 *
 * A page says where a part sits and how much room it has, never what it looks like. Tokens only
 * (global.css); spacing on the 4px scale; sans throughout, and the mono face only for an identifier
 * (`.feed-id`).
 *
 * THE KIT'S CONTROLS KEEP THEIR OWN LOOK. What is said of a `cloudcanvas-ui-*` class here is where it
 * sits and how big it is. The kit's sheet is added to the document after this one, so a rule that sizes
 * a kit button names two classes.
