CI / update (push) Successful in 52s
Previous behavior silently deleted static/shopping/*.svg when SHOPPING_*_NUMBER env vars were unset, then rsync --delete propagated the deletion to the prod server — the loyalty buttons disappeared on deploys where the env didn't reach the build (or during the brief rm→write window of a parallel run). Now the script exits non-zero with a clear message; deploy.sh's set -e aborts before any destructive sync.

/**
|
|
* Build-time generation of loyalty-card barcode SVGs.
|
|
*
|
|
* Reads card numbers from env vars and writes static/shopping/supercard.svg
|
|
* + static/shopping/cumulus.svg. Fails the build if any required env is
|
|
* unset so deploys can't silently ship a broken UI.
|
|
*
|
|
* SHOPPING_COOP_SUPERCARD_NUMBER → Data Matrix (Coop Supercard)
|
|
* SHOPPING_MIGROS_CUMULUS_NUMBER → Code 128 (Migros Cumulus)
|
|
*
|
|
* Run: pnpm exec vite-node scripts/generate-loyalty-cards.ts
