Handover

Summary

  • This repo is a static WebGL gradient demo with four standalone HTML entry points.
  • All four pages now share the same top navigation and debug/admin controls.
  • There is no build process; files are edited and served directly.

Files In Current State

  • index.html: demo variant 1
  • index-2.html: demo variant 2
  • index-3.html: demo variant 3
  • index-4.html: demo variant 4
  • Gradient.js: renderer, animation loop, uniforms, and runtime control API
  • controls.js: shared navigation and debug/admin control panel
  • controls.css: overlay styles
  • README.md: usage and feature overview
  • AGENTS.md: maintenance instructions
  • HANDOVER.md: current-state handoff

What Changed Recently

  • Added a shared on-page debug/admin overlay to all four demo pages.
  • Added top navigation between index.html, index-2.html, index-3.html, and index-4.html.
  • Added live controls for:
    • amplitude
    • wireframe
    • global noise frequency X/Y
    • global noise speed
    • vertex noise frequency X/Y
    • vertex noise speed
    • vertex noise flow
    • shadow power
    • darken-top toggle
    • all four colors
  • Added play/pause, reset, and panel collapse controls.
  • Extended Gradient.js with explicit runtime setters plus getState() and applyState().
  • Fixed runtime mesh wireframe syncing so the overlay can toggle it directly.
  • Added repo-local documentation:
    • README.md
    • AGENTS.md
    • HANDOVER.md

Source Of Truth

  • HTML entry pages define the page shell and page-specific CSS color presets.
  • Gradient.js is the source of truth for renderer behavior and uniform updates.
  • controls.js is the source of truth for the admin overlay and cross-page navigation.
  • controls.css is the source of truth for overlay presentation.

Runtime Notes

  • controls.js waits until the gradient instance has initialized its mesh and uniforms before mounting controls.
  • Reset restores the initial runtime state captured after the page is ready.
  • The overlay does not persist state between reloads.
  • ?debug=webgl still enables console-only debug logging in addition to the on-page controls.

Verification Performed

  • node --check Gradient.js
  • node --check controls.js

Known Gaps

  • I did not run an interactive browser pass from this environment.
  • The page <title> values do not currently align cleanly with the file names:
    • index-2.html title is Stripe Gradient 3
    • index-3.html title is Stripe Gradient 2
  • There is no persistence or export/import for control panel state.

Practical Next Steps

  1. Open all three HTML pages in a browser and confirm overlay layout, mobile behavior, and control responsiveness.
  2. Verify the new index-4.html color preset alongside the existing demos.
  3. Normalize page titles if the file-name mismatch matters for presentation.
  4. Add state persistence only if the user wants presets or sharable configurations.
