1// core/error-handling.js — extracted from app.js (lines 12008-12062).
2// Classic script: shares the global scope with every other core/ and features/
3// script. Do NOT wrap in an IIFE and do NOT convert to an ES module — top-level
4// function declarations must attach to window for inline on* handlers, and
5// top-level const/let are shared across files.
