- 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
