/*
 * THE FRAME'S OWN SURFACES: the user icon's dropdown and the sign-in gate. global.css owns the document and
 * the palette; engine.css owns the seam with CloudCanvas; the unified sheets own the shell and its views.
 * The settings dialog that once showed the account pane, the modal sheet that held its frame and the page
 * after them are gone: the dropdown is the one way in.
 * The legacy nav bar, toolbar, window body, panel frame and renderer sheets went with the legacy
 * panels (M1b).
 *
 * THE DESIGN LANGUAGE, in one place so every rule in every sheet is an
 * application of it rather than a fresh decision:
 *
 *   panels     opaque `--bg-raised` boxes: hairline border, `--radius-lg`,
 *              `--elevation-3` for a dialog.
 *   rhythm     the `--space-*` scale only.
 *   colour     tokens only. Signals use the `--*-wash` tints; nothing in any
 *              sheet states a hex value that global.css does not already own.

/* ------------------ THE USER ICON'S DROPDOWN (shell/account-dropdown.js) ------------------ */
/*
 * A column of rows and sections on the kit's popover, which places it, holds it to the screen and scrolls it. Its width is its own and never
 * wider than a phone: the popover's padding and margin are taken off the viewport. A row is the height of a target and keeps the check's column
 * whether or not it holds the check, so the words line up. A section opens under its row. Tokens only, so both themes are the palette's.
