From b5eb72343a7ae930b5ffd225f0c96fbe2da8495c Mon Sep 17 00:00:00 2001 From: jesse-ux Date: Sun, 18 Oct 2026 16:20:35 +0800 Subject: [PATCH] fix(kp): place exact angular boundaries on the opening subdivision Upstream 8eec9a54. Floating accumulation and a 120-degree remainder put star, pada, and sub-lord on different sides of the same boundary. Random longitudes away from those boundaries are unchanged. BUG-1383.
