The editor read as "poor" largely from border clutter — hairlines
everywhere. Strip incidental borders and let tonal surfaces + spacing
carry the structure:
- Toolbar: drop the bottom hairline (its surface tone separates it).
- Drawer: drop the seam line (both sides) — tonal separation only.
- Drawer panels: drop inter-panel divider lines (scope accent + spacing).
- Code block: drop the outline — the overlay surface fill defines it.
- Table: no outer box, no vertical lines — light horizontal row rules
only + airier cells.
- Drawer insert items: borderless soft tonal tiles (hover deepens with
the accent) instead of bordered boxes.
Kept the intentional lines (quote accent bar, the silver margin rule).
Verified in browser: no console errors; table is horizontal-rule-only,
insert tiles borderless.
