Desktop client reaches full feature parity with mobile for the two
heaviest sections. Contacts + Devices screen + polish pass remain for
rc1.
Feed section (src/sections/feed/ + src/lib/feed.ts):
* Left pane — FeedTabs: For You / Following / Trending 24h + a
hashtag input that promotes to a tab on Enter; breadcrumb back-
navigation when you drill into an author wall or hashtag.
* Right pane — FeedPane: two sub-columns. Scrollable post list
(truncated body, likes/views/hashtags footer, active highlight)
+ PostDetail with full body, hashtag links (click → hashtag tab),
inline attachment image, like/unlike button, Delete (if mine).
On-mount side-effects: bumpView + fetchStats for liked-by-me.
* ComposeModal — new-post dialog. Ctrl/Cmd+N opens it; Ctrl+Enter
submits. Byte counter against 4000 limit, live hashtag preview.
Uses publishAndCommit (server-side image scrub happens when
attachments land in rc1).
* lib/feed.ts — full mirror of mobile's feed.ts:
fetchForYou/Timeline/Trending/Author/Hashtag/Post/Stats,
bumpView, like/unlike/delete/follow/unfollow, publishPost +
publishAndCommit + buildCreatePostTx. Uses window.crypto.subtle
for SHA-256 (no expo-crypto dep). Same canonical-bytes as mobile.
Wallet section (src/sections/wallet/ + new bits in src/lib/api.ts):
* WalletOverview (left): account card (balance + shortened pub +
Send/Receive/Refresh) and transaction history grouped by row.
Amount colour-codes by direction; pretty tx-type labels.
* WalletDetailPane (right): selected tx — big signed amount,
2-column key/value grid (id, from, to, amount, fee, time, block,
gas), collapsible JSON payload + payload_hex fallback. Mirror of
mobile /tx/[id] layout.
* SendModal — transfer tx with @username / DC-address / hex pub
resolution via resolveAccount. Balance + fee preview; refuses
self-transfer (would roundtrip through mempool for no reason).
* ReceiveModal — pub + Copy button. QR in rc1 once we pull in a
qrcode lib.
* lib/api.ts: TxRow + TxDetail types, getTxHistory, getTxDetail,
resolveAccount (handles hex/@username/DC-address).
Store adds feedTab + feedSelectedPost + walletSel so selection state
survives section-switches. FeedTab discriminated union covers the
hashtag + author sub-states so breadcrumbs know what to render.
Typecheck + renderer build both pass. Node API used as-is — no
server changes in this release.
