Subject: [PATCH] fix: boot sequence lines appearing twice
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Two init paths both called runBoot() before sessionStorage was set
(the key was only written on completion, ~1.1s later):
- Private init() at DOMContentLoaded → runBoot()
- lt.init() HTML call on DOMContentLoaded → ltInit() → runBoot()

Both found no session key and started simultaneous setInterval loops
on the same <pre>, each appending the same message → every line twice.

Fix: set the sessionStorage key immediately at the start of runBoot()
so any concurrent second call exits early.
