/* Life Progress site styles.

   Palette lifted from the shipping app's theme tokens in
   ~/Projects/lifeprogress/src/theme/index.ts — `themes.minimal` for light and
   `themes.dark` for dark:
     minimal  #ffffff bg, #f5f5f5 bg2, #ffffff card, rgba(0,0,0,0.06) border,
              rgba(0,0,0,1) text, rgba(0,0,0,0.72) text2
     dark     #09090f bg, #0f0f1a bg2, rgba(255,255,255,0.06) card,
              rgba(255,255,255,0.10) border, rgba(255,255,255,0.72) text2

   The mint accent is the app icon's sun (~/Projects/lifeprogress/assets/icon.png,
   sampled: #82EBC5 at the crown fading to #56C7A1 at the horizon). #82EBC5 is
   used as-is on the dark ground, which is where the icon puts it (13.8:1 against
   #09090f). On white it measures 1.4:1, so the light theme uses #0E7C5A — the
   same hue deepened to 5.2:1, which is what src/theme/contrast.ts's
   deepenForWhiteText exists to do inside the app.

   The life-grid hero art's five stage colours are the shipping values from
   src/constants/life.ts STAGES:
     childhood #34d399, adolescence #60a5fa, youngAdult #fbbf24,
     middleAge #f97316, senior #f87171
   and the ten-cells-per-row layout is GRID_COLS = 10 in
   src/components/LifeGrid.tsx. Nothing here is invented.
