/* Founder window switch, version 2 (replaces founder-window.css, which keeps its bytes). Two rules, no display value is ever set.
   An element with fw-open-only is the founder-window text; an element with fw-closed-only is the text for after the window.
   Before the window ends, and with no script at all, the html element has no fw-closed class: every closed twin is hidden and every open element shows.
   After the end the script adds fw-closed: every open element is hidden and every closed twin goes back to the display its own page rule gives it (inline-flex for a .btn, block for a paragraph, and so on).
   The first version showed the twin with display: revert, which falls back to the browser's default instead of the page's own rule, so a flex button came out inline. */
