/* ===========================================================================
   Lore terms and their tooltips.

   This is the signature element of the site. It is also the thing most likely
   to be annoying if handled carelessly, because a dense paragraph of tagged
   terms turns reading into a minefield of accidental taps.

   Two presentations, one data source:
     pointer: fine    → hover popover
     pointer: coarse  → tap opens a bottom sheet

   A sheet rather than a popover on touch because popovers clip at viewport
   edges, land under the thumb, and are fiddly to dismiss.
