Brings core/ in line with components/ — each subsystem now sorts its files into
js/ css/ html/ subfolders (and the nested auth/ + controls/ groups keep theirs):
core/topbar/{js/{topbar,mobile-menu}.js, css/{topbar,sidebar}.css, html/topbar.html}
core/theme/{js/theme-registry.js, css/{tokens,themes,base,aurora-background}.css}
core/forms/{css/{forms,config}.css, controls/js/{custom-number,custom-select}.js}
core/boot/{js/{system-loader,system-orchestrator}.js, auth/{js/auth-manager.js,css/login.css}}
core/{config,tasks,kernel}/js/… core/overlays/{js,css}/… core/setup/{js,css}/…
core/{app-meta,backup-card,data-loader,dom,live,notifications,ui-mode,ui-state}/js/…
core/{loading,update-notifier}/{js,css}/…
50 files relocated (pure git mv). All path literals rewritten from a generated
old→new map across index.html, system-loader.js bundles, topbar.js's internal
fetch (/core/topbar/html/topbar.html), and the three backup-app-card loaders. No
OLD path contained a js/css/html segment, so no double-prefixing was possible.
core/icons/ left as-is (shared asset tree). All 50 /core asset refs verified to
resolve; full node --check sweep clean.
