Intelligence Layer
The skeleton is intentionally boring where it should be
We've standardized the patterns where taste is not allowed. Accessibility, performance budgets, and state completeness are your non-negotiable foundation.
Victory Visualization
Every success triggers a celebratory reward. Apply the Peak-End Rule to critical user milestones.
02
60fps Interaction
Use useMotionValue and useSpring for interaction tracking. Zero reconciliation overhead for 1:1 cursor tracking.
03
Fluid-First foundations
Mathematical scaling using clamp(), rem, and container queries (cqi) for truly modular components.
04
Performance Budgets
LCP < 2.5s, INP < 200ms. Mandatory thresholds ensure award-winning craft doesn't tank usability.
05
Vault Architecture
A personal full-stack vault to save 'cherry-picked' patterns found across reactbits and 21st.dev.

The Mastery Standard
Backed by actual constraints
"The standard is not 'make it fancy'. It is: know what must always work, then make the right few moments feel inevitable."
