/* D.R.E.A.M.S: "Fresh Water + Blueprint" design system (light)
   ---------------------------------------------------------------------------
   Fresh Water: airy light base, lake blue ink, coral from the boat's red hull,
   friendly display type, rounded cards, organic photo shapes, depth contours.
   Blueprint touches: red-pen markups (circles, detail callouts), title-block
   tables, a blueprint grid behind hardware, small mono labels in blue ink.
