/* ==========================================================================
   Lecture mode for EEG Fundamentals (components/fundamentals-lecture.js)

   The course as a slide deck. A dim, violet-black surround like a reading
   room at night; the slide is the lit page. The slide uses the site's own
   surfaces and type, scaled with the stage through the root size, so it
   reads the same in light and dark themes. The presenter controls around it
   are fixed in px so they stay put when the slide text grows. The one
   signature element is the timeline scrubber, drawn like an EEG page's
   time base: a tick for each slide and a tall gridline where each course
   section starts.
