#1316 already has an open PR aiming to address the issue of missing translation keys: #1290

This PR is also going beyond the scope of applying missing keys to strings, which is misleading from the PR title and description of a "focused change". Also, see my relevant comment from one of your other PRs here on these PR descriptions: #1391 (comment)

Thanks for pointing this out. You're right: I missed that #1290 is already open for #1316, and this PR also went beyond the narrow missing-translation-key scope described in the title/body. I'm closing this to avoid duplicating existing work and adding review noise. I've also paused the automation that opened these rapid-fire PRs and am updating the remaining open PR descriptions to use the project template with accurate testing/platform notes.
