From 0704027e6c1976b7ed675f861294a13e110c15de Mon Sep 17 00:00:00 2001
From: Seth Flynn <getchoo@tuta.io>
Date: Fri, 7 Nov 2025 01:01:11 -0500
Subject: [PATCH 1/3] build: install 256x256 png icons

This is required by `go-appimage` - and apparently(?) a requirement by
XDG, with SVGs being optional

Signed-off-by: Seth Flynn <getchoo@tuta.io>
