/* The Invoice screen (production-booking task 20, reworked in ui-clarity
   task 10; js/views/invoice.js). Reuses .panel and its collapsible toggle
   (app.css), .eyebrow / .ref / .fig, the menu button (menu.css), the Project
   page's .pf-chip, .pf-facts, .pf-notice(s), .pf-action-error, .pf-hint and
   its dialog (project-folder.css), the editor's line grid and picker for
   Extras (.billing-block, app.css, responsive.css), the detail's blocks for
   the accepted estimate, and .status-chip (calendar.css).

   The header sits on the page; everything below it is a panel (U2). The
   amount due is the screen's one big figure, in Delight, where the eye
   lands. One terracotta button: the header's primary (Send…, Mark paid…),
   or Save extras while the extras are unsaved, which takes it over.

   Written phone first:
     - under 768px: one column; the amount due under the overview, then the
       primary full width with Actions ▾ and Documents ▾ beside it; the
       panels stacked, the sum last;
     - 768–1099: the amount due and the actions on the right of the
       overview, as the Project page's header;
     - 1100 and up: the panels the wide main column and the sum beside them,
       held in view while the extras are edited. */
