This is separate from the existing rule that validates color-string settings.\n\n**Why**\n\nThis lets Claude Code catch invalid values earlier for settings that must be sized in character cells, giving a clearer error instead of accepting a malformed value.\n\n- Area: Elsewhere\n- Tier: Under the hood\n- Useful: 1\/5\n- Signal: 1\/5"}
