/*
 * NTWOOD — Style A "Rừng Sương" (Forest Light)
 * Dark, cinematic, nature-luxury. Taken from the catalog cover: fog forest,
 * light falling through timber louvres. One accent: the logo's DEEP green —
 * the bright logo lime read as glaring on the dark canvas (client, round 1).
 *
 * Contrast (measured): mist on ink 16.1:1 · mist-dim 7.4:1 · --green on ink
 * 6.05:1 (accent type, icons, lines) · white on --green-btn 4.97:1 and on
 * --green-btn-hot 5.50:1 (filled buttons) · wood on ink 6.5:1. --mist-faint is
 * for labels ≥ 12px uppercase only. Never put white text on --green (3.15:1).
