/*
 * NTWOOD — Style C "Xưởng Màu" (Material Studio)
 * Warm, tactile, colour-first. The visitor "tries on" the eleven wood
 * grains on a facade before asking for a real sample. Built for the
 * homeowner and the dealer who choose by eye.
 *
 * Contrast (measured on --cream #F3EDE3): espresso 14+:1 · text-2 8.7:1 ·
 * muted 4.9:1 · green 6.7:1 · white on green 7.8:1 · espresso on lime 11.3:1.
 * Lime is a SURFACE colour here (blobs, highlights), never text on cream.
