/*
 * NTWOOD — Style B "Bản Vẽ" (Spec Sheet)
 * The site reads like an architect's material dossier: drawing-sheet grid,
 * title blocks, mono spec data, cross-sections that draw themselves.
 * Built for the B2B visitor (architects, contractors) who came for numbers.
 *
 * Contrast (measured on --paper #EEECE7): ink 16+:1 · ink-2 7.1:1 · muted 5.0:1
 * · orange-ink 4.8:1. --orange (#E2531B, 3.2:1) is for LINES, fills and
 * display type ≥ 24px only — never small text.
