/* Keynote, round 3: an Apple keynote and product page. Vast white space, an enormous tight-tracked centred
   headline whose last line takes the scheme's gradient, a soft colour bloom behind it, full-bleed black
   chapters, gigantic numerals that rise into place, tiles that scale in, charts that wipe in, a product
   shot that tilts up as you scroll, and type that fills with ink as you read. Base: none.
   Knobs (body, or any tk-hero / tk-section to scope them):
     data-keynote-scheme   ocean (default) | sunset | meadow | graphite | spectrum | mono
     data-keynote-hero     glow (default) | stage | rings | plain        (body or tk-hero)
     data-keynote-chapters alternate (default) | dark | light            (body)
     data-keynote-ground   dark | light                                  (one tk-section)
     data-keynote-motion   on (default) | off                            (body)
   On Apple devices the SF system faces are used; elsewhere Inter Tight and Inter stand in. */
