The top-bar buttons looked heavy against the navy bar (thick grey X-circle, bold "Send" pill). Swapped for light SF Symbols on the navy bar: a thin `xmark` for cancel and a `paperplane.fill` for send (semibold, enables when ≥1 chat is picked). Icon-only send matches the Teams reference — the radio checks already show what's selected, so the "(N)" count text is dropped. Native-only — needs a build.

// Share Extension — puts "Biz Connect" in the iOS share sheet AND does the whole send right here, the way
|
||
// Teams/WhatsApp do: pick one or more chats in the sheet, it uploads and sends, no app-open needed.
|
||
//
|
||
// How it can send without the app: the app writes a bearer token + API base into the App Group each launch
|
||
// (via /api/share/token → ShareInbox.setAuth). This extension reads that token and calls the same server
|
||
// API the native client uses — GET /api/messages/conversations, POST /api/messages/upload, POST
|
||
// /api/messages.
|
||
//
|
||
// Manifest lifecycle (why the app doesn't also pop a "Send to" sheet): the App Group manifest represents an
|
||
// UNSENT share. We only write it when this extension can't send (no token) or a send fails — so a
|
||
// successful in-sheet send leaves nothing behind and the app never re-offers it. Cancel/success clear any
|
||
// staged files too, so the App Group doesn't accumulate orphans.
