- embed favicon.svg as a logo in the README
- add a prominent "no security — trusted networks only" callout
- sprinkle emoji through README/TODO/PLAN/NOTES headings; fix NOTES typo
- admin: maroon buttons use .danger class (white text); replace hardcoded
#333/#ff8a8a/drop-target colors with theme vars so light mode is legible
- time.ts: force hourCycle h23 (no 24:00 artifact), drop dead 24-guard
- Makefile/README: rsync with excludes instead of `cp -a .` so .git and the
dev DB don't ship to /opt; add rsync to deps
builds and installs the systemd service from a fresh checkout; substitutes
real node path / prefix into the unit. README documents it as the quick path.
