Initial commit — keysat.xyz landing site

Static HTML + SVG/PNG assets for the public marketing site at
keysat.xyz. Deployed via FileBrowser to the operator's StartOS at
websites/keysat-xyz-landing/.

Files:
- index.html — main landing
- support.html — Lightning donation + on-chain BTC for sponsors
- assets/ — SVG marks, PNG icon/thumbnail, favicon

Stack: hand-written HTML + CSS, no build step, no JS framework.
Matches the keysat-design-system tokens (cream paper, navy ink,
gold accents, Archivo display + Inter body + JetBrains Mono).

Private repo during alpha; will go public alongside v1.0 launch.
