#23 Hide Names & Avatars: extend blur to open thread header + in-thread sender avatars

[Anonymous]

Originally created by: kristofferR

Follow-up to [#17] (shipped in [#22]).

The initial "Hide Names & Avatars" toggle (hide_names_avatars, Cmd/Ctrl+Shift+N) blurs names, avatars, and previews in the conversation list — the primary screen-share privacy surface. PR [#22] deliberately scoped it there.

This issue tracks the remaining "ideally" surfaces from [#17] that were deferred because they need verification against the live Messenger DOM:

Behaviour

When the toggle is on, also blur:

• The open conversation's header — the contact/group name (and avatar) at the top of the active thread.
• In-thread sender avatars — the profile pictures shown next to incoming messages.

Implementation notes

• Reuses the existing html[data-carrier-hide-names] marker (already toggled in src-tauri/inject/messenger.js); this is CSS-only — add rules to src-tauri/inject/messenger.css.
• Verify selectors against the live DOM first. Avoid guessed deep selectors — that's exactly the stale-selector trap from the compact-mode bug (#20). Prefer stable anchors (ARIA roles, the thread-header region, a[href*="/t/"] where applicable) over churning Facebook class names.
• No new setting or shortcut needed — it rides the existing toggle.

Notes

• Pure CSS blur, no network interception — low risk, same as the shipped part.

Part of the Caprine privacy-parity set.
