QUESTION
Can the OSI model and ten common failures become inspectable scenarios instead of a memorized list?
WORKING ANSWER
A working learning surface built with vanilla web technologies, GSAP, bilingual content, and selected network simulations.
OPEN LIMIT
The content is strong; its loading rhythm and visual system need revision before this becomes a main case study.

03 RECORDS · 03 OPEN LIMITS
A result without a known limitis not a decision.
Each record pairs a working answer with the condition that can invalidate it. The same discipline shapes the decisions behind the selected product work.
