/**
* readerChrome.js — site-wide reader chrome (NOT part of the editor).
*
* Provides two always-available reader aids that used to live inside the
* Editor extension's siteNav.js:
* • [📚] document navigator (bottom-right FAB + panel)
* • [↑] scroll-to-top (appears after 300px scroll)
*
* Why it's separate from the editor: these are reading aids, useful on every
* page for every visitor — they have nothing to do with editing. Keeping them
* in the editor module meant they only made sense in edit context and leaked
* onto all pages awkwardly. This module owns them, loads site-wide, and the
* editor no longer touches them.
*
* Docslist is DERIVED from the JSON: namespace (NS 3000): every document has a
* JSON: page, so listing that namespace is the authoritative, self-maintaining
* document list. When the editor creates a new document (writes its JSON page),
* it appears here automatically — no hardcoded list to maintain.
*
* Install: add as a Gadget (or load via MediaWiki:Common.js /
* wgResourceModules) so it runs on every page. Requires jQuery + mediawiki.util
* (both default). The FAB image /images/docs.svg is optional (emoji fallback).
