• ad-creative (2.7.0 → 2.8.0): added AirDrop as a fourth surface in the iOS-native reveal video ad family (references/imessage-video-ads.md, alongside iMessage / ChatGPT / Apple Notes; format popularized by Shiv Sakhuja / Gooseworks' goose-video Airdrop Ads, re-expressed originally — their runtime is MIT but the recipe is private, so this is original craft). The one interaction-native format in the family: the hook is an incoming AirDrop request and the Accept tap is the reveal — a translucent AirDrop card (sender device name, preview thumbnail, red Decline / blue Accept) from the receiver's POV, where iOS's own accept/decline choice is a built-in micro-conversion beat. New ### AirDrop Reveal subsection: the preview thumbnail as the hook that must earn the tap, sender-name casting (relatable human name reads native; brand-as-sender reads like an ad), the transfer progress-ring as the signature motion, the AirDrop swoosh sound (not iMessage tritones) with the same CC0-Apple + trade-dress caveat, receiver-POV-default vs sender-POV-flex, and the family grounding/disclosure rules (a dramatization of a share, never a real endorsement). Updates the H1, intro, surface-selection table, and choosing-signal line to four surfaces. SKILL.md pointer names AirDrop and adds the 'AirDrop ad' trigger. New eval (id 11).
