/*
 * Stand-in for an absent operator branding stylesheet.
 *
 * index.html always loads /branding/branding.css last so an operator can
 * redefine the branding tokens from src/styles/branding.css. That file lives
 * in a bind-mounted directory and is normally not there; the nginx configs in
 * deployment/ answer the request with this bundled file instead, so a default
 * install serves an empty stylesheet rather than logging a 404 on every load.
 *
 * Intentionally empty of rules — every default lives in src/styles/branding.css.
 * Do not add styles here: this file is shadowed the moment an operator
 * installs their own branding.css.
