# Cache-busting marker for the rewritten JavaScript bundle.
#
# Seerr serves /_next/static/ as "public, max-age=31536000, immutable", and
# nginx's sub_filter strips ETag and Last-Modified off every response it
# rewrites, while the HTML naming those chunks is served "no-store" and keeps
# naming the same URLs. A browser therefore pins the bundle this add-on rewrote
# on its first visit for a year, with no request left that could deliver a
# later change to the sub_filter rules below - which is how #2975 outlived two
# fixes. Folding the version into the asset path gives every release its own
# URLs. njs/ingress.js strips the marker again before proxying.
#
# BUILD_VERSION is the add-on version baked in at build time (it is also what
# bashio::addon.version returns). Only [A-Za-z0-9-] survives: the marker ends up
# inside a regex literal in Seerr's own bundle, where a dot would be a wildcard.
