 * Messages view — per-view CSS (slice 2 of comms+network redesign).

 * Bespoke `.msg-*` class system mirroring the finance-aligned design
 * language already in `pwa/styles/inbox.css` (`design_finance_canonical`
 * memory). Three-pane CSS-grid shell at desktop widths; stacks vertically
 * below 768px so slice 9 can pick up real mobile polish.
