Estimated code review effort: 4 (Complex) | ~60 minutes Merge Risk: 🟠 High · up to The change can fail during deployment when existing tag data does not match the new relationship, and an unknown post URL can produce a server error instead of the intended response. These issues should be fixed before merging; several smaller empty-state and related-content behaviors also need correction. Sequence Diagram(s)sequenceDiagram

Apply title_x_text to the <h1> branch.
When a caller sets title_is_heading and title_x_text, the <h1> renders only the server value. The runtime title override works only for the <p> branch.

Render empty_message for an empty feed.
templates/v3/posts_list.html passes empty_message, but this include ignores it. PostFeedFilters.empty_message returns "There are no posts yet." for an unfiltered empty feed. The current copy incorrectly tells that visitor to search again. Update TestEmptyState.test_renders_for_an_empty_feed with the corrected expected title.

Issue: #2566
Summary & Context
Replaces the placeholder-illustration empty states with the text-based ones from
Figma, via one shared
empty-statecomponent rather than three per-page variants.The library-version state also gains the designed "Switch to latest" CTA, which is
only rendered when the library actually exists in the latest release, so it can
never point at another missing-version page.
Changes
templates/v3/includes/_empty_state.html- new shared partial: headline, optional hint, optional CTA.static/css/v3/empty-state.css- new component styles, plus--insetand--pagevariants.templates/v3/includes/_library_empty_state.html- drops the two beaver/moose PNGs for the text state.templates/v3/library_page.html-emptyStateMessage()split intoemptyStateTitle()/emptyStateHint(); the state is no longerhiddenwhen the server returns no rows.templates/v3/includes/_post_list_card.html- renders the empty state when the feed has no items.libraries/views.py,templates/v3/libraries/library-subpage.html- inline-styled TODO placeholder replaced; description copy and the latest-version CTA URL are built in the view.emptyStateMessage()would break; there are none in the tree.object_list; the empty state there still needs Alpine.
