DESIGN.md

Generated as educational analysis. Inferences are hypotheses, not source-code claims.

Observation

  • Observed colors: rgba(0, 0, 0, 0), rgba(255, 255, 255, 0.0), rgba(143, 143, 143, 0.67), #00000000, #000, rgba(200,200,200,0.1), rgba(56, 189, 248, 0), rgba(232, 232, 232, 0.2), rgba(143, 143, 143, 0.6719), rgba(236, 72, 153, 0), #ebeced, #6c6c6c
  • Observed font families: Helvetica

Inference

  • Repeated tokens may indicate a shared design system; external stylesheets were not executed or downloaded.

Recommendation

  • Define semantic color and type tokens before copying visual treatments.
  • Validate contrast and responsive behavior in the target product context.

IA.md

Generated as educational analysis. Inferences are hypotheses, not source-code claims.

Observation

  • Navigation labels: Pricing, Log in, Get started, Pricing, Log in, Get started, Pricing, Log in, Get started

Inference

  • Repeated navigation labels likely represent primary information architecture.

Recommendation

  • Model user tasks first, then test whether this hierarchy fits them.

COMPONENTS.md

Generated as educational analysis. Inferences are hypotheses, not source-code claims.

Observation

  • Observed forms: 1
  • Observed calls to action: Open main menu, Features, Company, Resources, Help, Docs, AI, Get started, Get started, Node.js, Serverless, Ruby

Inference

  • Repeated structures may be implemented as reusable components, but DOM output cannot prove source boundaries.

Recommendation

  • Next.js: /_next/
  • React: react

Inference

  • Technology detection is probabilistic because production builds can remove or disguise signatures.

Recommendation

  • Verify stack choices using public engineering sources before adopting them.

ARCHITECTURE.md

Observation

  • Analyzed 3 public page(s) on resend.com.
  • Public paths: /, /a16z, /about

DECISIONS.md

Generated as educational analysis. Inferences are hypotheses, not source-code claims.

Observation

  • Evidence base includes 3 fetched page(s).

Inference

  • Visible product choices suggest tradeoffs but do not reveal the original team’s rationale.

Recommendation

  • Record each decision with context, alternatives, consequences, and a review date.

Observation

  • Discovered path: /
