# FrameInGoa — every variable here is OPTIONAL.

# The app builds, runs and produces downloadable, shareable graphics with none of

# them set. They only light up the extras.

# --- Sharing (Route 1: "Post on X" with a link that unfurls the graphic) --------

# Provided automatically when you link a Blob store to the project on Vercel.

# Without it /api/cards returns a clean 503 and the UI falls back to the Web Share

# API and plain download instead of dead-ending.

BLOB_READ_WRITE_TOKEN=

# Public base of your Blob store, e.g. https://xxxxxxxx.public.blob.vercel-storage.com

# Used by /c/[id] to build ABSOLUTE og:image URLs. Without it the share page falls

# back to the site's own OG image, so the unfurl is never blank.

NEXT_PUBLIC_BLOB_BASE_URL=

# --- Canonical site URL (captions, OG metadata) --------------------------------

# Defaults to window.location.origin in the browser.

# Set this to YOUR deployment URL. On Vercel it is derived automatically from

# VERCEL_PROJECT_PRODUCTION_URL, so you only need this for a custom domain.

NEXT_PUBLIC_SITE_URL=

# --- Live builder counter (optional) -------------------------------------------

# Either the Vercel KV names or the Upstash names work. Absent = deterministic

# per-name fallback number, which is what most visitors will get anyway.
