Collapse the deploy sub-pages back into one deploy.md (tabs, not separate
pages), add a working mermaid flow diagram, and rework the top per feedback.
- Mermaid: enable via superfences fence_div_format (the fence_code_format
<pre><code> wrapper broke mermaid's render — div format fixes it); vendor
mermaid.min.js locally (no CDN dependency for a self-hosted site) + a small
init that renders each block once and survives instant-nav.
- Content tabs Compose / Dockerfile / Secrets hold the three pieces together
on one page (inline comments in the code, no annotation +).
- 'What can run here' tip moved above the flow; section renamed
'Preparing for Deploy' with the 'you don't run deploy commands' point folded
sparsely into the intro (standalone note removed); 'svc never changes'
called out.
- Flow diagram (below the tabs): build group now includes our libraries; git
-> staging shown as develop-if-gitflow (dotted); deployment (no MR-to-main)
-> docker image built + run on the fleet.
- Revert inbound links to deploy.md.
Verified in-browser: diagram renders with all nodes, tabs switch, section
order correct; mkdocs build --strict clean.
