a11y: add proper keyboard activation for share button

[Aarya-Chaudhari]

This PR improves accessibility by enabling proper keyboard interaction
for the social share button.

• Enter key activates the button on keydown
• Space key activates the button on keyup

This follows native button behavior and improves usability for
keyboard and assistive-technology users without changing UI or behavior.

Summary by CodeRabbit

• Style
  • Minor formatting cleanup in the share-button code (removed an extra blank line). No user-visible or behavioral changes.

Walkthrough

Removed an extra blank line in the createButton implementation of the social share button; change is purely formatting (fewer newlines) and does not alter logic, control flow, exports, or runtime behavior.

Changes

Cohort / File(s)	Summary
Formatting cleanup src/social-share-button.js	Removed one extra blank line between the innerHTML template and the subsequent this.button assignment in createButton. No behavior, control flow, or API changes.

Estimated code review effort

🎯 1 (Trivial) | ⏱️ ~2 minutes

• Quick check that only whitespace was removed and no tokens or semicolons were affected.

Poem

🐇 I nudge a line and make it neat,
A tidy hop, a tiny feat,
No logic changed, just fluff made slim,
A neat new pace for code to brim,
The rabbit stamps a quiet beat.

Learning: SSR compatibility is important for public libraries. For files under src/, ensure the SocialShareButton (and related public APIs) render correctly in SSR environments across frameworks. Check for browser-only globals, conditional code paths, correct hydration behavior, and that the library exports behave consistently when used in SSR.

Thanks for the review!

You’re right — native elements already support Enter and Space
activation. I’ve removed the redundant keyboard event listeners and now
rely on the built-in behavior.
