Hub (toolsntoys.html), JL's early tools (jl-early-tools.html), guides hub
(guides.html), FOSS Arsenal catalog (foss-tools.html), and 6 individual
guide pages covering AppImage, Linux install/uninstall, Docker, and
Facebook streaming. All pages use the night-sky adaptation of the
adventurers_toolbox3 aesthetic with dimmed ember alpha (0.38/0.65).
