Courses are translated, exported, re-imported into authoring tools, and released without visible technical errors. Linguistic checks may confirm that terminology appears correct and sentences are grammatically sound. Only after rollout do problems become visible.

Design debt does not arise from poor craftsmanship or lack of skill. It arises from design decisions that are optimized for a single-language context. In monolingual projects, certain shortcuts appear efficient: fixed layouts, text embedded directly into visuals, or logic tied to visible strings. These decisions often reduce upfront effort and speed up delivery.
