/* "Art" in the markup stays literally "Art" - each of the 39 morph steps
   below supplies its own text-transform (uppercase/capitalize/lowercase)
   to get ART/Art/art, so this no longer forces a fixed casing itself.
   Sized to its own content horizontally (not a fixed width) so the
   bounce-dot sitting right after it stays as close as the text allows.
   Height is fixed, though: the fonts have wildly different internal
   line-height metrics, and as an inline-block this element's own box
   height feeds directly into the surrounding line box - left alone, that
   made the whole line (and everything below it: the dash rule, the
   paragraph, the button) nudge up and down as the font cycled. inline-
   flex with align-items:flex-end pins the text to the bottom of that
   fixed box rather than letting each font's own line-height center it
   differently, which is what was knocking "Art" out of alignment with
   "Into" and the bounce-dot after the height got locked - bottom-aligned
   sits close to the shared text baseline for essentially any Latin font.
   Color is the ordinary body-text color, same as every other word in the
   headline - only the typeface and casing change. */
