/* ==========================================================================

   Editorial, not template. The page is one warm ground with hairline rules
   and asymmetry doing the structural work — no alternating background bands.
   Ink is used sparingly, for one deliberate moment per page, and the footer.

   Type: Fraunces (display, optically sized) over Instrument Sans (text).
   Corners are square throughout. Photography is never rounded.
