The card shows two verbs ("Try now" for rate-limited, "Summarize" for pending)
for one user intent, and — the real bug — a no-captions video falls into the
pending branch and wrongly shows a Summarize button that can only fail. Spec
collapses to one quiet "Summarize now" verb wherever a nudge is possible (both
handlers unchanged underneath), adds an honest no-button "No transcript
available" state, and keeps the card status-first (buttons are exceptions in auto
mode). View-layer only.
