From 6edab5c5c19aadeac6b7ace6d00b1b2e206a60ca Mon Sep 17 00:00:00 2001 From: shrimbly Date: Tue, 27 Jan 2026 22:01:38 +1300 Subject: [PATCH] feat(33): succinct chat responses and taller chat panel MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Rewrite chat system prompt to be concise — bullet points over paragraphs, 2-4 sentences per response. Make chat panel stretch from top-16 to bottom-[220px] for near-full canvas height.
