 - Runtime frontend is Blazor Server with interactive components.
 - Browser interop is in `RpgRoller/wwwroot/js/rpgroller-api.js`.
+- Root static assets such as `styles.css` are linked through Blazor's `@Assets[...]` pipeline so deploys get fingerprinted cache-busting URLs automatically.
 - Workspace reads are resolved server-side through scoped query services; browser interop remains for browser-only concerns such as session storage, SSE wiring, and DOM helpers.
 - Live workspace refreshes now compare separate roster, per-character sheet, and log versions so unrelated state changes do not force a full roster + sheet + log reload.
 - Workspace campaign data is loaded in bounded slices: visible campaign summaries, a selected campaign roster, a selected character sheet, and a 25-row incremental log window backed by `/api/campaigns/{campaignId}/log/page`.
