Root cause 1 (v1.12.18): `window.loadVoiceLibrary = () => loadVoiceLibrary()`
overwrites the global binding the arrow function references, causing immediate
RangeError: Maximum call stack size exceeded on every call. Changed to direct
assignment `window.loadVoiceLibrary = loadVoiceLibrary`.
Root cause 2 (v1.12.18): `loadSettings()` called `renderSettingsAbout()` which
lives in conversation.js (batch E), loaded after init.js. Guard added with
typeof check; nav.js already calls it safely when the About section opens.
Also (v1.12.18): s-library.html duplicated cl-book-filter / cl-search / cl-grid
from s-characters.html, breaking getElementById. Characters panel in Library
now redirects to s-characters instead of duplicating its DOM nodes.
Also (v1.12.19): engines.js triggers a second loadVoiceLibrary() after nav.js
already rendered voices, blanking the list briefly. Second call now silently
re-fetches without clearing the list when voices are already present.
