/* ═══════════════════════════════════════════════════════════════════
   Number Decoder (D106) — /Articles/NumbersInChineseCulture

   One page, one widget. Everything colour-neutral uses Bootstrap's own CSS
   variables so the decoder follows the site's dark mode with no second
   palette to keep in step; only the four verdict accents are stated here,
   and each is given as a translucent tint over the body background rather
   than a flat colour, so it reads on either theme.

   The prefix is "nd", never "ad" — a class or id containing "ad" is what
   content blockers match on, and a blocked widget looks like a broken page.
