   Hebrew to Suno - stylesheet

   EVERY COLOUR IN THIS FILE IS DEFINED IN THE :root BLOCK BELOW.
   Nothing further down hard-codes a colour. To restyle the site, edit only
   that block. The palette is sampled from yadayah.com so the two sites read
   as related: deep navy header, indigo band, gold accents, light neutral page.

   No external fonts, no CDNs, no build step. System fonts only.
