From 6244720c84cbcdff20190fb6713ce597133388db Mon Sep 17 00:00:00 2001
From: Sprite <noreply@sprite.dev>
Date: Sun, 8 Feb 2026 02:50:08 +0000
Subject: [PATCH] refactor: quote sleep delay variables for safety

Quote INSTANCE_STATUS_POLL_DELAY, SSH_RETRY_DELAY, and
SPRITE_CONNECTIVITY_POLL_DELAY to prevent potential word splitting
issues with unusual values.
