[Bug]: TypeScript typecheck fails in PlayOnScroll and CommunityMeetingsCardGrid

yarn typecheck at the moment doesn't pass due to TypeScript errors in two components.

1. PlayOnScroll

File:
src/components/utilities/PlayOnScroll/index.tsx

PlayOnScroll is defined as React.FC instead of using the current VideoProps type. This leads TypeScript to assume that the component does not take any props.

It results in the following errors in:
src/pages/features.tsx

for vidFormat, url, posterImg, and styles.

2. CommunityMeetingsCardGrid

File:
src/components/layout/CommunityMeetingsCardGrid/index.tsx

The logic for rendering markdown tries to access child.props after typing child as object. TypeScript complains that there is no props property on type object.

It breaks the parsing logic for extracting community meeting recording URLs.

Both problems block the repository from passing yarn typecheck

Start with src/components/utilities/PlayOnScroll/index.tsx and src/components/layout/CommunityMeetingsCardGrid/index.tsx, then run yarn typecheck to reproduce the reported errors. Check the usage in src/pages/features.tsx and the markdown child handling, and consider the issue complete when both components typecheck without breaking community meeting URL parsing.
