Inbox

blockcommunication
Boilerplate repo

Three-pane mail surface. Left rail: Compose button, folders (Inbox/Starred/Sent/Drafts/Spam/Trash) with unread counts, colour-coded labels with totals. Middle: searchable message list with sender, subject, preview, labels, attachment glyphs, star toggle, smart timestamps. Right: reader pane with subject, from/to, body, attachment chip, reply/forward/archive actions. Stateful demo — swap `mails` for your data source.
