Subject: [PATCH] fix: guard col I/J/K access for short rows in MTZ Excel
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

MTZ changed their Excel format — some rows have fewer than 10 columns,
causing IndexError on row[9] (brand, col J). Use conditional indexing for
cols I (8), J (9), K (10) so short rows parse with empty brand/type/min_box
instead of crashing on startup.
