/* ---------- Ratings as hearts ----------

   Ten hearts for a 1–10 rating, drawn by hand in ink, a little crooked,
   with the color stuck on slightly off the line like a sticker (the
   owner's pick of three styles). The picker (js/heartsInput.js) draws
   each heart as its own SVG so they can fill one after another; the
   display (heartsHtml, js/detailModal.js) is one element and two masks,
   as a grid can hold over a thousand cards.

   The masks tile two hearts (one tilted left, one right) and run the
   width of ten; the fill is the same row cut at the rating, so a 7.5
   from an imported file shows seven and a half hearts. */
