/**
|
|
* Compiled Template Cache
|
|
*
|
|
* Cached vorverarbeitete Templates (AST) statt nur finales HTML.
|
|
* Ermöglicht schnellere Re-Rendering mit unterschiedlichen Daten.
|
|
*
|
|
* Performance Impact:
|
|
* - ~50-60% schnelleres Template-Rendering bei Cache-Hit
|
|
* - Reduzierter Parsing-Overhead
|
|
* - Bessere Memory-Efficiency durch strukturiertes Caching
|
|
*
|
|
* Cache Strategy:
|
|
* - Template AST wird nach erstem Parsing gecached
|
|
* - Staleness-Detection via File-Modification-Time
|
|
* - Separate Caching für verschiedene Template-Varianten
