Demo tour: private trips and tailored routing

Private discovery starts at /private-trips with the same continent model as group, but trip cards emphasize custom pacing and on-request pricing.

Compare any published private package under /packages — for example Brazil or France entries from the seed catalog — to see how summaries and CTAs differ from fixed group departures.

Dashboard operators create private proposals from existing packages; after running the demo sync script, a shareable proposal URL is printed in the console for /proposal/[token].
