/* THEME — Blueprint. Engineering documentation: cool white and slate, a faint dot grid, cyan accents,
   uppercase micro-labels, crisp panels. By night it turns into an actual blueprint — deep blue with light
   lines. Inspiration: Stripe, Linear and Vercel docs; drafting paper. Playful only in the grid and the
   night mode; the point is precision. Fonts: Inter (everything), JetBrains Mono (code and labels). */
