The video half of a Live Photo: a short video with the same name as a
photo next to it (IMG_1234.HEIC + IMG_1234.MOV). SmugMug shows it as
a separate video.
How upload treats RAW files. Uploading RAW originals needs a SmugMug
Source subscription; without one, a JPEG rendered from the RAW (its
embedded camera preview) can be uploaded instead.
smugmug-cli auth: obtain a new access token through the browser and
store it. Uses the API key/secret from the existing config, else from
the environment/.env, else prompts. Creates the config if missing.
The config to run with: the config file with any credentials from the
environment (as a container gets them) put over its own. Without a file,
all four credentials must be in the environment. Never save this back:
use load_config_file for that, so environment credentials stay out of
the file.
