# KNELPerf -> Grav publisher — pushes perf intel to performance.knownelement.com.
#
# Grav (Cloudron app 8336f951) pages are markdown files; we write them
# directly via ssh -> docker exec into /app/data/user/pages/, then clear
# cache. Auth to the SITE is Cloudron SSO (org-restricted); publishing is
# file-based, no web login needed.
#
# What gets published (idempotent, safe to run from cron/automation):
#   performance/            home dashboard (latest risk brief + arbitrage
#                           verdict + baseline index + fleet table)
#   performance/reports/*   the three repo reports (AMT, desktop, scheduler)
#   performance/baselines/  per-host latest baseline summary tables
# Env: GRAV_APP_ID (default below), GRAV_HOST (ssh host, default VPS tailnet)
