/* ════════════════════════════════════════════════════════════
   APPLIED CRAFT — Design System

   Design rationale (Satorigraphics + Design Better perspectives):

   Color: Warm palette that deliberately subverts AI-category conventions.
   No neon, no gradients, no dark-mode futurism. Amber accent signals
   craft and warmth — the antithesis of cold tech blue. This is a costly
   signal: an AI brand that looks nothing like an AI brand.

   Typography: Serif headings (Newsreader) for editorial authority.
   System sans-serif for body — clarity and performance. The contrast
   signals "publication" not "startup." Uppercase letterspaced wordmark
   for architectural precision.

   Spacing: 8px base grid with spatial echo rhythm (Tom Koszyk's
   framework). Consistent multiples create subconscious harmony across
   disconnected layout sections. "Like the design is breathing in tempo."

   Layout: Entry-Proof-Action (Tom's three-beat persuasive structure).
   Hero = entry, Applied AI section = proof, Subscribe = action.
   Generous cognitive relief zones between sections.
