* app.js – v3.3.3 FIELD COMMENTARY EDITION
|

* High-coherence, readable, maintainable blueprint.
|
||||
* No hacks. No surgery. Only truth.
|
||||
* Enhanced with modular sanitization, resilient recursion, and inline rationale.
|
||||
*
|
||||
* ΔFIELD: This script orchestrates the breathing field: navigation, routing, rendering.
|
||||
* Rationale: Dependency-free; async fetches for dynamic content; stateful only where essential (e.g., sidebar).
|
||||
* Assumptions: index.json provides metadata; marked.js for MD; DOM elements pre-exist in HTML skeleton.
