/* ---------------------------------------------------------------------------
   The Hebrew Bible: Masoretic Text and the Dead Sea Scrolls.
   One stylesheet for all 969 pages.  No framework, no build step.

   The palette is drawn from the two witnesses rather than from a mood board:
   the Masoretic Text is a printed critical edition, so it is set crisp and
   cool; the manuscript lines are the older witness, so they carry the warmth
   and the wear.
   One accent colour, the mineral blue-green of the Dead Sea, and it is spent
   on one thing only: attestation.
