/* =========================================================================
   PICKET THILL FIELD NOTES — « carnet de terrain » design system, prefix pt-
   Vocabulary: the naturalist's journal and the river, in French as a
   signature: berge (content bank = width), couverture (notebook cover =
   header), boite (fly box = nav), frontispice (typographic title page =
   hero), cours (numbered reach = section), fiche (observation card = card),
   etiquette (specimen label = card caption), journal/sortie (outing log =
   dated feed), ouverture (article head), planche (plate = lead image),
   colonne (reading column), releve (measurement table), station (data
   post, dark box), note (field note box), derive (the drift = read next),
   index (back of book = footer), symbole (inline SVG glyphs: dry fly,
   feather, rod, track), ornement (rule separator).
   Palette: willow green + river ochre + pebble grey + cream paper.
   No blue, no remote font, no gradient device, no photo hero on the home:
   the frontispice is pure typography, like a naturalist's title page.
   Dark mode is automatic. ========================================================================= */
