# Re-export the Expo web frontend for the Tauri desktop shell.
#
# Runs from src-tauri/ as Tauri's beforeBuildCommand, or from desktop/ by hand.
# `frontendDist` points at ../app/dist in the repo root, so a plain release
# build of an unchanged tree simply re-bundles the last committed export —
# exactly like the web deploy copies app/dist to the VPS.
#
# Node 22 only (matches app/.nvmrc and CI): newer npm writes lockfiles that
# CI's npm 10 refuses, so force the hermes node 22 toolchain if present.
