/* Partners: one clean sheet, every class `p-`.
 *
 * The look is Requests' (apps/requests/app.css), which is Field's iOS layer
 * taken as final values: the same --f-* tokens and the same SF type scale
 * (renamed --p-*). Three layouts from one tree (CLAUDE.md design brief):
 *
 *   phone   (<768)   one column, cards stacked, upload is a bottom sheet;
 *   iPad    (768+)   a centred 680px column, cards 2x2, the sheet a modal;
 *   desktop (1024+)  a 320px summary pane beside the 2x2 grid in 1080px.
 *
 * Rules that hold everywhere:
 *  - nothing interactive is smaller than 44pt in either dimension;
 *  - safe areas on every edge (env(safe-area-inset-*));
 *  - both themes through the tokens; a FILLED control is --f-fill with white
 *    text (4.6:1), never the bright accent;
 *  - no input under 16px (iOS zooms);
 *  - no inline style attributes anywhere (CSP style-src 'self').
