myoperator-design

Generates production-ready React/Tailwind CSS code matching the myOperator design system. Code is standalone — does not require the myoperator-ui package but visually matches its components. Always include the full CSS variables block in output.

Design Philosophy

myOperator's design language is professional, clean, and purposeful:

• Blue-gray primary palette (#343E55) — sophisticated and business-appropriate
• Turquoise accent (#2BBCCA) — fresh, modern brand identity
• Clean typography with Source Sans Pro — readable and professional
• Subtle interactions — focus rings, hover states, smooth transitions
• Semantic color usage — success/error/warning states are clear and consistent

The aesthetic is enterprise SaaS — trustworthy, efficient, uncluttered. NOT flashy, NOT playful, NOT experimental.

Brand Color Usage

Turquoise (#2BBCCA) is ONLY for:

• Focus rings on inputs
• Active/selected states (toggle switches, nav items)
• Interactive badges (e.g., "Live" indicator)
• Links and clickable text

DO NOT use turquoise for: charts, graphs, decorative elements, large backgrounds, non-interactive content.

For charts/graphs: use --semantic-primary (#343E55) as default data color. Use semantic state colors for meaning (success green = positive, error red = negative).

Color System

Always include this :root block in generated output. For the full primitive color scale (50–950 steps), see references/design-tokens.md.

Typography

Font: 'Source Sans Pro', sans-serif — always import with weights 400;600;700.

Convention: Default body is 16px. Use 14px for secondary/helper text only. 12px for rare metadata.

Output Format

Always output complete, runnable code:

1. Single file preferred — inline <style> tag with CSS variables + JSX component
2. Two files for larger components — styles.css + Component.jsx
3. Include useState/useEffect when the UI needs interactive state
4. Include SVG icons inline rather than importing packages
5. Plain JSX by default — only TypeScript if the user asks

// Recommended single-file structure
const css = `
  @import url('https://fonts.googleapis.com/css2?family=Source+Sans+Pro:wght@400;600;700&display=swap');
  :root { /* all tokens */ }
  body { font-family: 'Source Sans Pro', sans-serif; }
`;

export function MyComponent() {
  return (
    <>
      <style>{css}</style>
      {/* JSX */}
    </>
  );
}

Implementation Rules

1. Always include CSS variables — full :root block in every output
2. Never hardcode colors — always var(--token-name) references
3. z-index for overlays: always z-[9999], never z-50
4. Disabled states: use --semantic-disabled-* tokens, not just opacity-50
5. Focus states: focus-visible:ring-2 on all interactive elements
6. Transitions: transition-all duration-200 for hover/interactive states
7. Border radius: rounded (4px) for buttons/inputs, rounded-lg (8px) for cards/modals
8. Spacing: p-6 cards, py-2.5 px-4 buttons, px-4 py-2.5 inputs

What NOT to Do

• No hardcoded hex colors — always use CSS variable tokens
• No generic fonts — always Source Sans Pro
• No z-50 for modals — must use z-[9999]
• No turquoise in charts/data viz — use primary blue-gray
• No rounded-full on containers — only on badges and avatars
• No flashy animations — subtle transition-all duration-200 only
• No heavy shadows — shadow-sm for cards, shadow-lg for modals only
