README: document today's shipped work (story reactions/comments, per-pet insights dashboard, DESIGN.md/PRODUCT.md design system, admin panel visual pass) in "What's Shipped" and the admin panel section. docker/rolling-deploy.sh and start.sh were tracked as 100644 (no executable bit) since this repo is worked from Windows, which never records it — every fresh git pull onto the Linux NAS made them non-executable again. Fixed via git update-index --chmod=+x so this doesn't recur.

# Zero-downtime rolling deploy for the pawfeed-1/2/3 replicas.
|
|
#
|
|
# Builds the shared image once, then restarts each replica one at a time,
|
|
# waiting for the Docker healthcheck (GET /api/health, see
|
|
# docker-compose.yml) to report "healthy" before moving to the next one.
|
|
# At every point at least 2 of 3 replicas are serving traffic, so NPM's
|
|
# least_conn upstream (docker/npm-upstream.conf) never has fewer than 2
|
|
# healthy backends. `docker compose up -d --build` (start.sh) still works
|
|
# for a first-time deploy or when downtime doesn't matter — use this
|
|
# script for routine deploys against a live site instead.
