feat(site): lead the hero with the desktop app and add a cursor-aware particle field - #86
Conversation
… particle field - Remove the shields.io npm downloads badge from the hero. - Offer the desktop download for the visitor's platform directly in the hero, reusing the existing desktopDownloads constants, and demote the CLI install command to a secondary path below it. - Move the legacy Python downloads milestone out of the hero; it competes with the download call to action and advertises the previous product. - Add ParticleField: a canvas of small dots that drift behind the page and move away from the pointer. It sits at z-index -1 inside #app, so it never covers content, and it does not mount at all under prefers-reduced-motion or on coarse pointers.

How do review limits work?CodeRabbit enforces per-developer PR review limits for each organization. Most developers receive the normal plan review availability. For paid Pro and Pro+ PR reviews, CodeRabbit uses adaptive limits for sustained high-volume activity. When a developer's recent PR review activity reaches the 95th percentile or higher among CodeRabbit users, additional reviews become available more gradually as earlier reviews age out of the rolling window.

📝 WalkthroughWalkthroughThe landing page adds an adaptive particle background and changes the hero to show platform-aware desktop downloads, an all-downloads release link, and a separate CLI installation label. The legacy downloads popup moves to a milestone footnote. ChangesLanding Page Updates
Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk: 🟡 Moderate · up to On high-DPI displays, the new particle background can render at the wrong CSS size and leave particles concentrated in part of the viewport.

width and height to the viewport dimensions (for example, 100%) while retaining
the DPR-scaled canvas.width and canvas.height backing store in resize. Ensure
the displayed canvas matches the viewport on high-DPI screens without changing
the particle rendering logic.

Included review availability: Your plan includes up to 3 reviews per rolling hour; 0 remain after this review.
The canvas sets width and height attributes scaled by devicePixelRatio. Those give the element a specified size that inset: 0 cannot shrink, so on a 2x display the box was twice the viewport and the dots covered only the top-left quadrant. Percentages resolve against the fixed containing block and, unlike 100vw, exclude the scrollbar gutter.
