The browser tab still showed Wiki.js because only favicon.ico + 16/32 were
replaced — the larger icons the tab picks (android-chrome-192, apple-touch-180,
mstile-150) were still the defaults. Add ThreadNet versions and subPath-mount
them. Adding these pushed the single branding ConfigMap to ~1.04 MB (the 1 MiB
etcd limit), so split the 604 KB background into its own platform-branding-bg
ConfigMap mounted at /_assets/img/bg; authLoginBgUrl follows.
Set the blue Docusaurus-style accent (#2b6cb0 light / #63b3ed dark) via injectCSS
on the app UI — the login page is excluded because Wiki.js renders it without
custom CSS, so a dark login card is not themeable and is left as-is. Mount the
ThreadNet favicon (favicon.ico + favicon-16/32 PNGs the browser tab uses) from the
platform-branding ConfigMap via subPath, overlaying only those files.
Flux's default source ignore excludes *.png/*.jpg, so the platform-branding
configMapGenerator failed with "no such file or directory" for the branding
assets. Re-include just those two files via .sourceignore.
