   Wovenstack v2 — styles.css

   CONCEPT
   White page, black ink, short sentences set big. Every system is a thread:
   grey and dashed while it works alone, green and solid once Wovenstack
   connects it. Product panels are the only imagery. Peach stays in the logo.

   Order: 1 Tokens · 2 Reset/base · 3 Atoms · 4 Chrome · 5 Sections (shared)
          6 Components (panel, stage, switchboard, …) · 7 Page sections
          8 Motion helpers · 9 Responsive · 10 Reduced motion
