Sheet Layout
Sheet Layout is layered — mirrors the layered house-rules model:
Account default at /settings/layout. New characters snapshot this layout at creation. The page heading says "Default Sheet Layout".
Per-character override at /characters/{id}/layout (also linked from the character sheet's ⚙ Settings menu → Sheet Layout). Customizing here only affects that one character.
The character sheet picks the first non-null layout: character override → user default → seeded system default.
Sidebar Sections
For each section: move up / down with arrow buttons, or toggle visibility with the switch.
Tab Order
The right panel has 6 tabs (Spells, Equipment, Features, Companions, History, Notes). Reorder them or hide tabs you don't use. The configured order actually drives rendering — the sheet wraps its panels in a loop over the configured tab list.
Controls
Save — persists the current layout (to AppUser on /settings/layout, or to the Character on the per-character editor).
Reset to My Default (per-character only) — clears the override so the character falls back to your account default.
Reset to System Default — restores the seeded section order and visibility (bypasses both layers).
