   Palette and type kept from the Figma UI KIT (Indigo Dark #2B2038, Lilac
   #AC6CFF, Honey #F8D57E, Orange #FF9900; Poppins + Pretendard).
   Landing page composed under the design-taste-frontend sheet
   ("The product performs", seed 1217786059): no gradients, no resting
   shadows, no hairlines, no eyebrows, no numbering; interface fragments are
   marked data-ui and keep the product's own conventions.
