Pondevelopment LLM Training Theme Compliance

name: theme-compliance description: Audit and fix theme compliance issues in HTML and JS files — raw Tailwind color utilities, hardcoded hex/RGB values, inline styles, and incorrect getCssVar usage. Use this when asked to "audit colors", "check theme compliance", "fix raw Tailwind", "fix hardcoded colors", or when lint:js-colors reports violations.

Theme Compliance Audit & Fix

Goal

Ensure all papers, questions, and site-wide HTML/JS files use the semantic design system tokens (CSS custom properties, panel/chip/toggle classes) instead of raw Tailwind color utilities or hardcoded hex/RGB/HSL values. This enables consistent dark-mode support and theme switching.

When to use

• After creating or editing a paper/question with colored UI (bars, charts, badges, conditional styling)
• When npm run lint:js-colors reports violations
• When performing a bulk housekeeping pass
• When a visual regression appears in dark mode

Quick check

# Run the JS color linter to find violations
npm run lint:js-colors

# Run full lint (includes HTML, CSS, JS colors, and repo validation)
npm run lint

The two violation categories

1. HTML: Raw Tailwind color utilities and hardcoded colors

Problem: Classes like bg-indigo-50, border-blue-200, text-red-600 or inline style="color: #ef4444" break theme switching.

Solution: Replace with semantic theme classes:

Audit command:

# The HTML linter catches <style> blocks and inline styles in fragments
npm run lint:html

2. JS: Hardcoded hex colors in interactive scripts

Problem: Lines like element.style.backgroundColor = '#10b981' or fill: '#6366f1' ignore the active theme.

Solution: Use the getCssVar helper with a hardcoded fallback:

const getCssVar = (name, fallback) => {
  const v = getComputedStyle(document.documentElement).getPropertyValue(name).trim();
  return v || fallback;
};

// Usage
element.style.backgroundColor = getCssVar('--tone-emerald-strong', '#10b981');

Audit command:

npm run lint:js-colors

Auto-fix command (use with care):

node scripts/fix-js-colors.js           # Apply fixes
node scripts/fix-js-colors.js --dry-run # Preview only

Common token mappings

To discover more tokens, inspect css/theme.css for --tone-*, --color-* custom property definitions.

getCssVar critical rules

1. Define at IIFE top scope, after 'use strict', never inside init(). Sibling functions like updateUI(), renderChart() need access. Defining inside init() causes ReferenceError.

2. Always provide a fallback — the second argument is a literal color value that works if the CSS variable is missing:

   getCssVar('--tone-emerald-strong', '#10b981')  // ✅
   getCssVar('--tone-emerald-strong')              // ❌ no fallback
   

3. SVG template literals — wrap in ${} interpolation AND quote the attribute:

   // ✅ Correct
   `stroke="${getCssVar('--color-border', '#e5e7eb')}"`
   
   // ❌ Wrong — raw function call, no interpolation
   `stroke=getCssVar('--color-border', '#e5e7eb')`
   

4. Never use raw var() in JS-generated inline styles:

   // ❌ Unreliable cross-browser
   element.style.color = 'var(--tone-emerald-strong)';
   
   // ✅ Resolves the value first
   element.style.color = getCssVar('--tone-emerald-strong', '#10b981');
   

Full audit workflow

1. Run linters:

   npm run lint:js-colors   # JS violations
   npm run lint:html         # HTML violations
   

2. Review violations — the JS linter outputs file paths and line numbers.

3. Apply fixes:

   • For JS: use node scripts/fix-js-colors.js for bulk fixes, or manual edits for complex cases.
   • For HTML: manually replace Tailwind classes with semantic tokens (no auto-fixer).

4. Verify:

   npm test                  # Full lint + E2E
   

5. Visual smoke test — check both light and dark mode in the browser, especially charts, bars, and conditional coloring.

Checklist items (from PAPER_CHECKLIST.md / QUESTION_CHECKLIST.md)

• getCssVar helper (if used) defined at IIFE top scope, not inside init()
• No raw Tailwind color utilities in HTML — use semantic theme classes
• No hardcoded colors in JS — use getCssVar('--token', '#fallback')
• No <style> blocks or inline style="" in HTML fragments
• Dark mode renders correctly (no invisible text, no clashing backgrounds)
