/*
 * style.css — the holding page's look: Planet's viewer background, the name centred, quiet.
 * In:  index.html's single heading.
 * Out: one screen at any width, no scroll, readable on a phone.
 * Decision: #0b0e14 is the viewer's own background, so Phase 2's framed globe will sit on the same dark (WS · D3).
 * Built in W1 — Ground (24 Sep 2026).
