{# --- Images gallery ------------------------------------------------------- #}
{# Existing images are reorderable (drag) and removable; the kept set is #}
{# submitted in order as repeated `existing_images` ids. New uploads accumulate #}
{# across separate "Add images" clicks into a DataTransfer that backs the hidden #}
{# `image` input (a native file input would otherwise replace its selection on #}
{# every pick); the controller stores and appends them after the kept images. #}
{# Unified drag-orderable gallery: existing images (with id) and new uploads #}
{# (placeholder blobs) live in a single list. The full order is submitted as #}
{# repeated `image_order` fields — an integer id for kept images or `new` for #}
{# each uploaded file. The DataTransfer backing the hidden `image` file input #}
{# is rebuilt after every reorder / add / remove so the file-part order matches #}
{# the relative order of `new` slots in `image_order`. #}
