In `@website/vercel.json`:
- Line 6: The ignoreCommand currently uses "git diff --quiet HEAD^ HEAD -- ./"
which only checks the last commit; update the "ignoreCommand" in vercel.json to
use Vercel-provided env vars by replacing that command with a git diff that
compares ${VERCEL_GIT_PREVIOUS_SHA:-$VERCEL_GIT_COMMIT_SHA} to
${VERCEL_GIT_COMMIT_SHA} (or equivalent safe fallbacks) so the full pushed
commit range is checked and multi-commit pushes that touch website/ are
detected; ensure the updated ignoreCommand references the
VERCEL_GIT_PREVIOUS_SHA and VERCEL_GIT_COMMIT_SHA environment variables and
falls back safely for new branches.

Summary
ignoreCommandtowebsite/vercel.jsonso Vercel only builds previews when thewebsite/directory has changesgit diff --quiet HEAD^ HEAD -- ./(Vercel's recommended approach) which exits 0 (skip) when no files changed, exits 1 (build) when they didContext
Vercel creates a preview deployment for every push to every branch by default. Since only the
website/directory is deployed to Vercel, pushes that only touch Pascal source, tests, or other files outsidewebsite/don't need a preview build.
