Replace generic slate/indigo dark theme with a custom editorial
direction: warm paper neutrals, oxblood signal, Fraunces serif
display, Inter body, JetBrains Mono for codes. SVG paper-texture
noise overlay and thin rules across the app.
Refactored: Home, Settings, JoinRoom, Pair, Share, plus every
modal and panel (DropZone, DevicePairingPanel, PublicRoomPanel,
ProfileSetup, TextShareModal, ReceiveDialog, TransferProgress,
PeerList, PeerAvatar).
Also drops three pre-existing Uint8Array/BlobPart strictness
errors so the production build is green again.
