Summary
A .kra-adjacent artifact named Bundle_99 is handed off for analysis. It turns out to be a Krita resource bundle (.bundle) — a plain ZIP archive containing a brush preset (Brush 99.kpp). The .kpp file is itself a PNG with an embedded XML Preset block in its metadata. Buried inside dozens of harmless paintop parameters is a kis_text_brush definition whose text attribute contains the flag — Krita lets you generate a brush that stamps out literal text, so the flag was simply typed into that field and saved as a custom brush.
Flag: bronco{REDACTED}
