BASE — width-neutral identity of the chrome (header / menus / footer) and of the shared .ap-* / widgets content system. No size-varying values live here except width-neutral defaults that the band blocks below re-state per band. 2. UNIFIED SITE CHROME — the white sticky header + solid footer skin, Lora @font-face, the Palatino/Lora font law. 3. WHITE PAGE CONTENT — the flat white/grey-band content skin for the nine pages. 4. THE FIVE VERSIONS — SHARED LAYER — five sealed, double-bounded @media bands (PHONE ≤768.98 · TABLET 769–1024.98 · MACBOOK 1025–1599.98 · WIDE 1600–2099.98 · XWIDE ≥2100) carrying every size-varying value of the chrome + shared content system. The retired gold-era design was DELETED from this file on 2026-07-14 (git history keeps every old revision — commit c4e53b0 and earlier). index.html, about-music.html and studio/index.html carry their own page-local
