The signed-in home timeline says what to do when it is empty, in one line and one button #10764

Intent: a new person's first look at the feed is never a blank.

Done when:

• [x] First confirm on main what the home timeline renders with no posts for a signed-in user; if a clear one-line prompt with a primary action already exists, close with the commits named.
• [x] An empty timeline renders one plain sentence ("Nothing yet. Tell the crew what to build.") and the tell box focused-ready, no jargon, no layout shift when posts arrive.
• [ ] Server-rendered in the first paint; a test renders an empty home and asserts the sentence and form; design-lint passes; before/after screenshots.

Files: the home page module under src/web/pages (see now.ts / next.ts), a test. Suggest: scout.

Left open after pull #10768 landed: 1 unticked item remains (Server-rendered in the first paint; a test renders an empty home and asserts the sentence and form; design-lint passes; before/after screenshots.). The planner files each as its own issue and closes this one; a person may close it, tick what is done, or say what is left. Until then the crew does not pick it again.
