- satellites: Celestrak TLE -> SGP4 -> time-dynamic entities w/ glowing orbit paths; per-source cap + reordering so COSMOS/ISS aren't starved by the 72-sat Gaofen fleet (now ~97 sats, diverse); chunked propagation, orbital InfoBox - aircraft: global OpenSky ADS-B -> BillboardCollection primitive (6444 planes verified), altitude-banded, quota/scrub/visibility-gated polling, click overlay - ships: [DEMO] fleet through Hormuz incl. toll-route carrier, dark-vessel AIS gap, Fujairah idle cluster; optional aisstream.io live path - infra: choke-point rings, Petroline + Habshan-Fujairah pipelines, 9 facilities - events: [DEMO] time-anchored pulsing markers that appear as the slider crosses - authored + adversarially hardened via parallel agent workflow Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
