# CI guard: verify that bun --compile binaries can decode HEIC + AVIF.
#
# heic-decode bundles its libheif WASM as base64 inside libheif-bundle.js, which
# bun --compile preserves correctly out of the box. @jsquash/avif loads
# avif_dec.wasm via a path relative to its own JS file, which FAILS inside a
# compiled binary — the workaround is to pre-init the module with bytes loaded
# via `with { type: 'file' }`. This guard ensures both paths actually work in
# the compiled artifact, not just in dev mode.
#
# Mirrors scripts/check-wasm-embedded.sh from v0.19.0 (tree-sitter pattern).
#
# Wired into `bun run verify` (which `/ship` and `bun run test:full` call).
