   YouTube Thumbnail Downloader (/youtube-thumbnail-downloader)

   Built on the Backlink Maker design system: the page root carries both
   .bm and .ytd, backlink-maker.css supplies the hero, workbench, input,
   buttons, toast and info cards, and this file adds
     1. the letter-Y accent (az-color-palette.js primaryForLetter("Y") =
        #f79250), matching /youtube-backlinks-generator;
     2. the video card, the sizes list, batch cards, crop tool and the
        YouTube mock-ups.

   --bm-accent-strong (#97552a) is the accent darkened for text: 5.9:1 on
   white. The accent itself is decoration only.
