   oceanmagicframe.com — "DEEP FIELD LOG"
   Hero: full-bleed cinematic frame, masthead floated over it,
   copy anchored to the bottom-left with a depth-gauge rule.
   Article: a field-log grid — plate numeral hangs in the
   margin and travels with its entry, heading leads, image
   follows, paragraph closes. Quotes cut to abyss-dark bands.
   Type: Petrona (display serif) / Figtree (text)
