Upload
A packet is one zip: one .json + one .mp4
(and/or a frames/ folder of images). The JSON describes the
clusters; PortalSpinner figures out the rest —
packet spec.
Files open locally in your browser; nothing is uploaded.
Or drop a raw .mp4 — PortalSpinner breaks it into frames and you draw all the masking yourself:

Projects
A project is your working copy of a packet. Edits live on each page until you press Save; saves stay in this browser tab for this session. The exported package embeds your project file so you can continue later — you are responsible for keeping what you export.
Interactive test
Tests saved work only. Wheel-scroll like the real homepage; hover shows the portal; click follows the route.
Scroll feel
Selected timeline
Drag thumbnails to reorder — the left panel follows.
Portal links
Each portal is tagged by its text overlay (set on the Overlay page). Give each tag the page it should open.
