From 337cbcf76d9315e21c6e545429490bf574d79b14 Mon Sep 17 00:00:00 2001 From: Bissbert <43237892+Bissbert@users.noreply.github.com> Date: Mon, 18 May 2026 10:57:25 +0700 Subject: [PATCH 1/2] chore(ux): remove em-dashes and filler phrasing from site copy Em-dashes converted to commas, semicolons, or parentheses throughout.
