/*****************************************************
WORKSHOP MODE

Live presentation bullet highlighting: when active, list items are revealed one
at a time using keyboard controls.

Internal — for instructors and grad students presenting, not documented for
site authors.

Loads:    every page
Used by:  the inline script in html/html-js.html

Note: as of this writing nothing can switch workshop mode on. The script is
gated on `page.url contains '/guides/'` or `page.workshop_mode`, and there is
no guides/ directory (the docs moved to /docs/) and no page sets the flag.
Set `workshop_mode: true` in a page's front matter to use it.
Needs:    base.css tokens (--overlay-dark, --text-on-photo, --font-mono)
Not here: the nav checkbox markup itself (nav/nav-top.html)
