/* johnmartines.com — the page is a dive. Sky and surface at the top, shallow water,
   a thermocline, then the deep and the bottom of the lake.
   Colors come from the Portico theme kit (17 palettes x 24 shades x 3 contrast
   levels): theme-init.js writes every token below onto <html>, measured for
   contrast. The hex values here are only the fallback if the scripts never run:
   Newton & Elk, "Light". Rules use tokens, never hex. Text sits only on grounds
   the contrast check measures: --bg / --bg-alt / --raised up top, --deep-1 /
   --deep-2 / --deep-raised below the thermocline. */
