C12 and C13 come from one grid from the Level underside + 127 at 250 mm, up to top − 400 mm (상면 여유). The fixed count of seven rows is kept only for callers that give no top. P1 is unchanged (C12 5, C13 2); a taper of 3000 mm now gives C12 11 and C13 2, and the C13 first row is always the last C12 row plus 250. Co-Authored-By: Claude Haiku 5.5 <noreply@anthropic.com>
