Create AISTATS 2026 project page with integrated narrative, media-first layout, and appendix highlights

[Copilot]

This PR adds a GitHub project page for the AISTATS 2026 Spotlight paper using a Nerfies-style structure with custom storytelling. It reorganizes the paper content into a media-first, scan-friendly narrative that surfaces both core results and underexposed appendix findings.

• Project page foundation

  • Added a new root index.html as a standalone GitHub Pages entrypoint.
  • Implemented a responsive single-page layout with clear section anchors and compact navigation.

• Media-first opening (requested simulations)

  • Added a top “Trajectory simulations at a glance” section with 4 videos:
    • simulation/starmen/hand_going_down/sample_1.mp4
    • simulation/starmen/hand_going_up/sample_1.mp4
    • simulation/Adni/sample_417_trajectory.mp4
    • simulation/Adni/sample_451_trajectory.mp4

• Paper content reframed for project-page storytelling

  • Added sections for:
    • abstract,
    • integrated method storyline (problem → path construction → uncertainty modeling → downstream utility),
    • contributions and headline results.
  • Rewrote content for web consumption (shorter narrative units, emphasis blocks, higher information density vs paper prose).

• Figure integration from repository assets

  • Integrated figures from /figures into method/results flow:
    • embedded PDFs: fig1.pdf, fig2.pdf, fig5.pdf
    • raster figures: fig3.png, fig4.png, fig6.png
  • Added figure-specific PDF fallbacks to preserve correctness when inline PDF rendering is unavailable.

• Appendix insights surfaced explicitly

  • Added a dedicated “Often-missed insights from the appendix” section covering:
    • component-level ablation takeaways,
    • temporal generalization behavior across horizons/datasets,
    • 2D→3D generalization impact and consistency trends.

Example of the embedded figure fallback pattern used:

<object data="figures/fig5.pdf" type="application/pdf" aria-label="Figure 5">
  <p style="padding:1rem;margin:0;">
    Figure 5 preview unavailable.
    <a href="figures/fig5.pdf">Open Figure 5 PDF</a>.
  </p>
</object>

The shared CSS rule for object sets width/display but no height/aspect-ratio. Embedded PDFs rendered via often default to a very short height (or inconsistent sizing across browsers), making figure previews hard to read. Consider adding a consistent min-height or aspect-ratio (optionally via a dedicated class) so the PDF embeds render at a usable size.
