When a card is scanned, the public profile can open with a full-bleed,
AI-generated welcome hero before the contact info — experience #10 from the
scan-experiences brief, on the share-token experience selector foundation.
Backend (cardclaws-backend):
- migration 0005_welcome.sql: add cards.welcome JSONB; flows through
PublicProfile via serde flatten.
- POST /v1/cards/:id/welcome (owner-gated): refine + generate via the existing
AiClient (nano-banana), store {kind, message, imageDataUrl}.
- card_service::set_welcome + queries::update_welcome; CardRow gains `welcome`.
- 2 tests (generate→public-profile, ownership); workspace gate green (116 tests).
- Verified live with real Gemini end-to-end.
Web (cardclaws-profile):
- WelcomeHero.astro: full-bleed AI hero + greeting + "scroll to connect" cue.
- [handle].astro renders it when the card has a welcome; experience selector
(?x=profile suppresses) as the lever for the other experiences.
- PublicProfile gains an optional `welcome`; astro check clean.
MVP inlines the image as a data URL; production swaps to an R2 URL (isolated in
the welcome column).
