// ---- REGRESSION: PlantUML hex encoding ----
|
|
// Bug: ArchitectureTab had a broken encoding chain (rawDeflate returned input unchanged,
|
|
// encode64 was hex encoding masquerading as base64). Fixed by collapsing to single
|
|
// plantumlEncode function using ~h hex prefix (plantuml.com text encoding standard).
|
|
//
|
|
// This test validates the encoding algorithm matches what ArchitectureTab.svelte uses.
