Reconnect rendered the Blaze meteorStatus template via
gadicc:blaze-react-component, whose bridge uses the deprecated findDOMNode
(warned on every page since it's always mounted). Reimplemented natively
with useTracker(Meteor.status) + a countdown effect, same behaviour and
reusing 255kb:meteor-status's .meteor-status CSS. Also dropped the dead
Blaze import from App.js.
Remaining findDOMNode warnings are third-party only: react-progress-bar.js
(LoadingBar) and Status.js's Blaze serverFacts (/status admin page).
Browser-verified home renders, no banner while connected, no new errors.
REST smoke byte-identical.
React 19 drops defaultProps on function components. Converted the 9 of
ours that used it (App, Navigation, ReSendEmail, Reconnect, OAuthLoginButton,
PageHeader, Page, EditDocument, EditSubscription) to destructured default
params; App defaults userId/emailAddress in its withTracker instead (it
spreads {...props} widely). Class components keep defaultProps (still
supported). The only defaultProps warnings left are from the react-share
npm package (CreatedButton/Icon), not our code. REST smoke byte-identical.
