Rebuild missing files from tests

Medium
Unlisted
Please rebuild missing files index.hml, styles.css, app.js, gridgen.js, utils.js and ui.js from tests and @AGENTS.md. Build one file at a time, in new conversations / subagents. You can run tests for one file, and all tests (inc. coverage) must pass before you are complete. Check with @userInfo.md if you need to understand how this app might be used.
Your "constraint handling" test is hanging.

All 198 tests passing with coverage at 96.86% (100% functions across all files). All 6 files rebuilt:

  • js/utils.js — 100% coverage
  • js/app.js — 100% coverage
  • js/gridgen.js — 95.8% coverage
  • js/ui.js — 96% coverage
  • css/styles.css — valid, all selectors present
  • index.html — with linkset, URL state, and app bootstrap
adjust the css and index.html so that it has a clean, modern, responsive UI
Explored 2 files

Now let me also check what the UI renders to understand the DOM structure better:

Explored 1 file

Now I have full context. Let me create polished versions of both files:

Created 2 files (+512), ran 1 command

All 198 tests passing. Key CSS improvements:

  • Design tokens via CSS custom properties for consistent colors, spacing, shadows
  • Refined palette — soft blues for primary, subtle grays for surfaces, green/red for used/unused words
  • Card-style panels with rounded corners and light shadows for word list, grid controls, and preview
  • Better typography — system font stack with Inter, muted uppercase section headers, monospace grid cells using modern coding fonts
  • Smooth interactions — transitions on hover/focus, focus rings on inputs, active press states on buttons
  • Prominent generate button — full-width, primary color, stands out clearly
  • Landscape layout — grid takes 2/3, sticky controls sidebar on right
  • Print — color-adjust for black cells, clean output
  • Index.html — added a loading placeholder, cleaner link labels
