/* ==========================================================================
   Diamond Hall, Jerusalem. Bilingual landing page (Hebrew RTL at /, English
   LTR at /en/). Light-first: warm ivory ground, sand bands, charcoal text,
   gold only as a thin accent. The logo is a transparent gold PNG derived from
   the supplied JPG, so it sits straight on the ivory with no box.
   Logical properties throughout so one sheet serves both directions.
