- Around line 69-74: Add a new property definition for "cumulative-losses" to
the properties schema so the YAML entry in
packages/factbase/data/things/meta-ai.yaml validates and renders correctly: open
packages/factbase/data/properties.yaml and add an entry keyed
"cumulative-losses" mirroring the financial formatting used by "cash-burn" (use
the same type/format/units/label fields as "cash-burn" to ensure currency/number
formatting and display), include a brief description and any relevant aliases,
and commit the change; ensure the property name exactly matches
"cumulative-losses".
