Add `focus_beacon_span`, `panel_title_spans`, `panel_hint_style`, and `panel_border_style` utilities to centralize panel header, hint, border, and beacon rendering. Integrate these helpers across all UI panels (files, chat, thinking, agent actions, input, status bar) and update help text. Extend `Theme` with new color fields for beacons, pane headers, and hint text, providing defaults for all built‑in themes. Include comprehensive unit tests for the new styling functions.
