#!/usr/bin/env bash
# tools/stage-web-assets.sh — copy the runtime-fetched product assets into a
# web bundle's `assets/` directory.
#
# The wasm bundle deliberately omits these (see `op_editor_core::web_assets`):
# the browser fetches each on demand from `/pkg/assets/<dir>/<file>`, which the
# daemon serves straight out of the resolved bundle directory. The desktop
# binary still embeds them with `include_bytes!` / `include_str!`, so this
# script exists only for the web deployment.
#
# The layout under the destination MUST match the route literals in
# `prompt_center_previews.rs`, `scene_template_previews.rs`,
# `scene_template_catalog.rs` and `icon_catalog.rs` — those are `concat!`ed at
# compile time, so a mismatch is a silent 404 per asset rather than a build
# error. The Rust side pins its half with route tests; this script is the other
# half.
#
# Usage: tools/stage-web-assets.sh <dest-assets-dir>
# Exit: 0 staged, 1 a source directory is missing.
