# Frontend-track project prep: copy the skill's shared utilities into the
# project's src/utils/ and strip the Astro starter cruft that ships with the
# blank template. This is local-project (frontend) work, not backend seeding —
# the orchestrator only runs it in scaffold mode (integrate mode has no
# skill-written frontend to prep, so it is never invoked there).
#
# Usage (both modes work):
#   bash <SKILL_ROOT>/scripts/seed-utilities.sh --template astro
#   bash <(curl -s https://dev.wix.com/skills/wix-headless/scripts/seed-utilities.sh) --template astro
#
# --template (optional, default astro): astro
#   Astro is the only frontend the skill scaffolds and preps, so the value is
#   always "astro". Custom (non-astro) frontends route to the not-available stub
#   (references/custom/INSTRUCTIONS.md) and never reach this script.
#
# Run from the project directory (CWD = <scaffold>/). The script auto-detects
# whether shared-utilities is available on disk (tgz install) and falls back
# to fetching from the well-known URL when streamed via process substitution
# (BASH_SOURCE is /dev/fd/N, so the on-disk lookup naturally falls through).
#
# Behavior:
#   - Copies the three shared utility files into src/utils/ for both templates —
#     never overwrites an existing file (users can drop in their own version).
#   - On --template=astro, removes Astro starter cruft (Welcome.astro + marketing
#     SVGs) that ships with the blank template but is never imported by the build
#     skill.
#
# Shared utilities copied:
#   - wix-image.ts  — media URL resolver (used by stores, blog, cms)
#   - analytics.ts  — event tracking (used by stores, ecom, blog)
#   - ricos.ts      — Ricos JSON to HTML renderer for SSR Astro pages
