Poem

The docs now tell a tale anew,
Of actors built and queues that grew.
The status changed, the loop’s alive,
In connection.rs they now arrive!
Huzzah for clarity, progress shown—
Our outbound messages have a home.

32-35: Implementation Status now mirrors reality—well done.

The wording is concise, free of 1st/2nd-person pronouns, and lines respect the 80-column wrap rule. No further action required.

Hey @leynos - I've reviewed your changes - here's some feedback:

• The make nixie step is currently failing due to a missing puppeteer-core module—please update the build or dependencies to keep CI green.
• Verify that the [Section 3](#3-core-architecture-the-connection-actor) anchor still resolves correctly after the doc changes.
• Consider adding a brief code snippet from src/connection.rs to illustrate how the initial connection actor and write loop are implemented in practice.
