   ACCOUNTS
   Chart of accounts grid, the timeline, and the A4 document preview.

   Part 4 of 11, cut from the 5,142-line app.css. THE ORDER OF THESE
   FILES IS LOAD-BEARING — they are one cascade, split for navigation only, and
   index.php links them in this sequence. Moving one changes which rule wins.
