Platform-Specific Handling

• LinkedIn: Copies text to clipboard, prompts user to open LinkedIn (API doesn't support pre-filled text)
• Bluesky: Uses intent/compose web intent with URL-encoded text parameter
• Mastodon: Prompts for instance, constructs instance-specific /share URL
• Download: Shows instructions for right-clicking the SVG chart (avoids canvas conversion complexity)

Backend (src/extension.ts)

• shareToSocialMedia(platform): Handles share logic with platform-specific URL construction
• downloadChartImage(): Displays instructional dialog
• Message handlers for webview communication

Frontend (src/webview/maturity/main.ts, styles.css)

• Share section HTML with event listeners
• Platform-specific button styles with gradients and shadows
• Grid layout: auto-fit minmax(200px, 1fr) for responsive behavior

Original prompt

Instant to build "share to social media" buttons in the fluency chart that allows you to share the chart+fluency levels to LinkedIn, Bluesky, Mastodon. If it's possible to share each item (chart, each aspect separately) then I would want that to be the default. Else, share the image as a whole.

Include a link to download the extension from the marketplace to show your score. Add a unique hashtag for our extension so we can subscribe to it.
