CellCounter Web 0.2.1 preview — continuous scientific landing page

The introduction is now a continuous, full-page composition. A microscopy-inspired point cloud changes with native scrolling through See → Separate → Measure → Work, with clear text and direct access to the workspace.

• Cool-white surface, charcoal typography and restrained blue-gray particles replace the boxed animation.
• Cell-like forms become separated objects, then boundaries and an ordered field as you scroll.
• Persistent section links, rotation, reset and Pause controls; reduced motion uses static stages.
• Mobile layouts place the illustration below the text. The renderer loads only for the introduction, limits rendering cost, pauses in background tabs, and releases its resources on workspace entry.
• Native scrolling works over both the text and the illustration; no wheel hijacking or forced scroll stops.

The particle forms are labeled illustrations, not measurements or segmentation output. Local classical segmentation and the saved preview, processing, review and export workflows from Web 0.2.0 remain available. Learned-model weights are still not bundled; this design release does not claim full native-platform parity.

Production build and release checks passed in CI. The desktop and mobile compositions, native scrolling, stage controls, Pause and workspace entry were exercised in the production preview. Reduced-motion and failure paths were code-reviewed.
