The fact that `speeches.css` and `app.css` both contain styles from the Foundation source (rather than foundation.css being its own file) have been a source of modest annoyance over the last few days. But admittedly, this is the first time I've had to hack my way round it.

Sorting the whole mess out, as you suggest, didn't seem worth it just to fix these breadcrumb slashes. But if you think it's important (or you too have been annoyed by CSS inheritance in sayit.mysociety.org) then maybe we should do it? In a new branch though.
