   Identity: "Routine Layers". Skin-care basics ordered by routine step
   (01 Cleanse -> 02 Treat -> 03 Moisturize -> 04 Protect), drawn as horizontal stacked bands
   like skin layers in cross-section, with undulating boundaries between strata. Product pages
   print the full INCI list in a monospace "label strip" with the key ingredients highlighted.
   Palette: blush-neutral ground, deep brown ink, mineral teal accent, blush + sand strata.
