/* Warp design system — authored in-house for Asquad B2B export templates.
   Design DNA: Warp DESIGN.md — warm near-black canvas, Warm Parchment (#faf9f6) text,
   almost-monochromatic warm grays (no bold accent colour), Earth Gray (#353534) pill
   buttons, uppercase editorial micro-labels (letter-spacing 1.4–2.4px), semi-transparent
   borders instead of shadows, terminal/monospace accents. Matter is a proprietary font;
   per DESIGN.md fallback chain we substitute Inter (geometric sans) for body/display and
   Geist Mono for the terminal/code accents. NOT a copy of Warp's content — design
   language only. Terminal-geek aesthetic for tools / hardware / machinery / automation. */
