+On user request, Accounts and Network adopt Serial's compact label/value grids, form styles, help typography and action spacing. Account/key/Network summaries are semantic definition lists populated with DOM text; all information remains available. Printable ASCII SSIDs remain quoted, other bytes use hex, and value cells preserve significant spaces while wrapping. Key textarea, generated-password field and checkboxes share form styling. IDs, request/operation behavior, warnings, secret clearing and terminal/lease ownership are unchanged.

+Parent validation PASS: UI **100 behavior groups**, HTML structure/renderer/header/CSP, and headless Chromium geometry/whitespace regressions at **320/600/1200px**. Review's SSID space-collapse issue was corrected and regression-tested. Final `pio run` **23.69s**, **99,548 B RAM / 1,744,325 B flash**, **+0/+1,744** versus the preceding readable-ASCII summary build (1,742,581 B flash); diff check PASS. These are fixture-based browser checks, not on-device visual acceptance. No backend/generated-asset/upload/erase/commit action.
