Fixes the screenshots on the for/education page to have the
canonical last name for the example user Elena Garcia.
Updates year in dates for screenshot content to align with when
the screenshots were taken.
Adjusts the width of the viewport for changes in the message
header bar in the web app. Also closes any alert banner at the
top of the app before navigating to the narrow so that doesn't
impact the cropped screenshot area that's computed later.
Finally, sets hover on the new conversation button so that none
of the message action buttons are visible in the message feed
when the screenshot is taken.
This commit extends the script used to generate thread
screenshots to be able to create invite_only streams,
add starred messages, create user groups, add edited
notice to messages, and send messages from notification
bots.
The window width is updated, and background for the
screenshots is changed to white.
It is also updated so that user-avatars mapping
occurs within the script itself.
This is a prep commit to #30128
Previously, we manually generated screenshots on /for/research
and other landing pages, which makes them difficult to maintain.
This PR adds a script - generate-user-messages-screenshot, which
expects the path of the filename containing the thread conversation
and path where screenshot needs to be generated, and generates
screenshot at the mentioned location.
Fixes#30016
