+## [TEST] Bot test block (ignore)

+This paragrah has intentional errrors: teh word "occurred" is misspelled as "occured", and "separate" as "seperate". The rest of the sentence is correct: we run Security Analysis, Simple checks, Typo, and Build workflows. Size labels (XS/S/M/L/XL) are applied automatically. You can safely close this PR without merging.
