/* ============================================================================
   SADER — SECTION: PILLARS  (s-pillars)  ·  "Our Culture"
   A DIAGEO-hero composition reimagined classic, dark and STRICTLY MONOCHROME:
   a white line-art founder floats centre as the hero object under a top-centre
   spotlight, the ground falling to black at the edges (chiaroscuro); an
   editorial serif headline sits upper-start; three quiet glass cards scatter
   asymmetrically around him; a fine hairline "plinth" seats the figure.

   Synthesised from a multi-variant design pass (spotlight base + museum-plate
   plinth/numerals/sub-label + token-discipline grafts). Colour comes ONLY from
   the dark-theme tokens + white-alpha — no warm / gold / brass tint anywhere.
   Logical properties throughout, so the same markup mirrors for the RTL build.
   Reuses tokens + .section / .container / .eyebrow / .section-head.
