From 7ce5d94b5d48b68c86d015060ebcabe63e299e1a Mon Sep 17 00:00:00 2001 From: Gabriel Schneider Date: Mon, 28 Sep 2026 16:24:59 -0300 Subject: A selection holds up to 1024 ranges on the desktop, 64 on the board The limit was 64 everywhere, which helix-golf's enumerate_and_align outgrows (%s |\d+ makes 121 ranges). It is now memory.limits.selections, per platform, and the counts that hold it are u16. The ranges stay inline in each Text, so a pane grows by about 80 KiB on the desktop (three texts and the regex prompt's snapshot); the Pane size budget in Terminal.zig moves from 128 to 160 KiB and says why.
