Ship goa-amount.js inside each landing tree, add an inline fallback when
the asset is not yet deployed, keep CHF free of GOA unit names, fix
exchange amount_full wiring, and add test-landing-stats.sh (local + live).
Add a host-side Python collector that lists every bank account, pages
through all ledger rows, and emits stats.json with amount_alt fields
(Kilo/Mega/Peta-GOA) so large ladder withdrawals fit on the landing tiles.
