README covers what alembic does, prerequisites, a full deploy quickstart,
credential setup, and a page-by-page usage tour, written for someone
running Docker but not necessarily comfortable coding or sysadmin work.
Favicon/icons were prepared in a separate theme scratch dir but never
wired in; moved them into app/static and pointed base.html at the full
icon set (SVG, PNG fallbacks, apple-touch-icon, manifest) instead of the
single inline data-URI SVG it had before.
