Why this tripwire exists

Catches the silent regression where a dash.dare.co.uk deploy loses the inline thumb-pop + data:image base64 payload. Added 2026-06-05 after an ad-hoc deploy overwrote a healthy 2.4 MB / 113-thumb build with a 303 KB / 0-thumb one and the hover-preview UX silently went dark. RED when live thumb-pop count drops below 10% of the local pre-deploy count.
