  🎨 Rethink Your Jira Experience
  
  Stop straining your eyes with the default Jira white. Prisma is a professional-grade themer designed specifically for Atlassian Jira, giving you full control over your workspace's visual identity without compromising performance.
  
  Unlike generic dark mode extensions that simply invert colors and break layouts, Prisma integrates directly with the **Atlassian Design System tokens**. This means faster loads, no "white flicker," and a native-feel experience—just in your favorite colors.
  
  
  ⚡ Key Features
  
  – Native Performance: Built on top of Jira's own design tokens for a seamless, lag-free experience. No layout shifts or broken icons.
  – True Dark Mode: A meticulously crafted dark theme that respects contrast and accessibility standards.
  – Unlimited Customization: Don't just settle for 'Dark.' Create 'Deep Sea,' 'Forest,' 'Cyberpunk,' or your own brand-aligned theme.
  – Variable-Level Control: Tweak specific groups - Surfaces, Borders, Text, and Brand colors to get the perfect look.
  – Custom Presets: Save your favorite color combinations and switch between them instantly.
  – Privacy-First:w Your data never leaves your browser. Prisma stores all settings locally and doesn't require an account.
  
  
  🧩 Why Prisma?
  
  Most themes break when Jira updates. Prisma is built to be resilient by targeting the underlying design tokens rather than brittle CSS selectors. It's the "set it and forget it" tool for developers, project managers, and power users who live in Jira.
  
  
  🔒 Privacy & Safety
  
  – No Tracking: We don't track your usage or collect your data.
  – Local Storage: All theme settings are stored securely in your browser.
  – Minimal Permissions: We only request access to `atlassian.net` domains to apply your styles.

  Make Jira easier on your eyes
  
  Prisma adds dark mode and custom color themes to Jira Cloud, so your workspace feels calmer, more personal, and easier to use during long work sessions.
  
  Unlike generic dark mode extensions that invert colors across the page, Prisma is built around Atlassian Design System tokens. That helps the theme feel native to Jira instead of breaking icons, issue statuses, boards, and other UI details.
  
  Features
  
  - Better dark mode: Reduce glare in Jira Cloud during long work sessions.
  - Custom color themes: Tune surfaces, borders, text, and brand colors.
  - Saved presets: Save favorite color combinations and switch between them.
  - Native-feeling styling: Built around Atlassian design tokens instead of broad page inversion.
  - Privacy-first: No account, no tracking, no analytics.
  - Local settings: Theme preferences stay in your browser.
  
  Why Prisma?
  
  Jira is a tool many developers, project managers, and team leads keep open all day. Prisma gives you more control over how it looks without turning Jira into a messy inverted-color page.
  
  Use it to reduce glare, match your workspace to your preferred colors, or create a theme that feels better for daily work.
  
  Privacy
  
  Prisma does not collect your data. Your theme settings are stored locally in your browser. The extension requests access to atlassian.net pages only so it can apply your selected theme to Jira Cloud.
  
  Compatibility
  
  Prisma is built for Jira Cloud on atlassian.net domains. Self-hosted Jira Data Center is not currently supported.
