# Canonical web bundle build: Trunk plus a fonts sanity sync.
#
# Trunk's copy-dir pipeline always copies web/fonts in full, but its final
# "apply staging to dist" step wipes the old dist and then moves dist/app/.stage
# into place. If that wipe fails on Windows (typically a transient lock from a
# local file server or antivirus with a file open under dist), the build exits
# non-zero and leaves dist stale with .stage fully populated — easy to miss,
# and a stale bundle would 404 the fonts the app fetches from fonts/*.ttf.
# This wrapper therefore re-syncs web/fonts into dist/app/fonts after a
# successful Trunk build and verifies every font byte-for-byte, so a bundle
# produced through it can never ship without the font set.
#
# Usage: sh scripts/build-web.sh [extra trunk build args]
#   local:  sh scripts/build-web.sh
#   CI:     sh scripts/build-web.sh --locked --html-output index.html web-app.html
