Restores the 208 catalog items reverted after their previews 404'd in production, this time on the payload mechanism rather than the .html files that caused the outage. The generator no longer writes a preview document to docs/public. That writer, and the machinery under it, existed only to produce files the docs host discards, so it is gone rather than bypassed. Items now embed the composition itself via a payload, which is what the previous change already does for the items that were already in the catalog. The variables explorer is parked, not restored: it drove its preview through the same unpublished .html path, so it would have shown an empty frame. Items that declare variables get the live player plus the static variables table, and reconnecting the explorer to payloads is a follow-up.

Parallax Zoom — center card scales up while siblings parallax outward.
|
||
|
||
Inspired by the eBay Playbook hero transition: a grid of cards collapses
|
||
as the focal card grows to fill the frame.
|
||
|
||
Usage:
|
||
1. Wrap your card grid with class="parallax-zoom-grid".
|
||
2. Mark each card with class="parallax-zoom-card".
|
||
3. Add data-pz-row="0|1|2|..." and data-pz-col="0|1|2|..." per card
|
||
so the snippet knows each card's grid offset.
|
||
4. Mark the focal card with data-pz-focus="true" — this is the one
|
||
that scales up to fill the frame.
|
||
5. Drive --pz-progress 0 → 1 on the .parallax-zoom-grid from your
|
||
composition's paused GSAP timeline (see example at bottom).
|
||
|
||
Tunable CSS variables on .parallax-zoom-grid:
|
||
- --pz-focus-scale (default 6) maximum scale of the focused card
|
||
- --pz-sibling-push (default 900px) outward translation strength
|
||
- --pz-sibling-fade (default 1) sibling opacity falloff (0–1)
