Hard-coding static asset urls is brittle because the place the files are stored depends on the `STATICFILES_STORAGE` used - so if in prod the storage backend uploads to S3 or even renames the file then this hard-coded URL will break.

Using "{% static ... %}" solves that as it knows exactly where the files are stored.

So in practice, do this

    # in index.html
    {% load static from staticfiles $}
    <img src="{% static 'logo.png' %}" />

Instead of this

    # in index.html
    <img src="/static/logo.png" />
