{% comment %} SPEC §5's four counters as headline cards, for the flow stats page. The broadcast page deliberately does not include this: its figures come from `broadcast.stats` via `apps.broadcasts.services.counters` and mean something narrower — one send's recipients rather than a node's lifetime — so sharing the markup would have implied a shared definition that does not exist. `clicked` carries clicks-per-send beneath it wherever there were sends to divide by — "where buttons exist" in the issue's words, expressed as "where anything was counted" so a flow whose only link is inside an email body reads the same as one with a button. It is labelled a ratio rather than a rate, and can legitimately read over 100%: `clicked` counts clicks while `sent` counts messages, and SPEC §18 keeps no per-contact history, so one recipient pressing a link three times is three. {% endcomment %}
