/* Beaudoin Photography
   Palette taken from the archive itself: the library measures ~48% neutral —
   snow, bark, stone, sky — so the chrome is built from those greys and the
   accent is lichen green, the colour of the fence posts and trunks that recur
   through the work. Dark is the primary ground; photographs sit better on it.
   Type: Newsreader for voice (field journal), IBM Plex Sans for interface,
   IBM Plex Mono for catalogue data — species counts, dates, hex values. */
