Reskin GregKilmer.com in the Patiun brand

- Palette: Patiun Teal, Midnight, night sky, Starlight, flat Alchemist Gold;
  violet/indigo only as nebula light. Starlight content sections, night-sky
  nav and heroes (.on-sky scope re-points accent/gold to on-dark values).
- Type: Cinzel for headings, names and card titles; Montserrat for body, UI
  and eyebrows (font-eyebrow); JetBrains Mono kept for code-like blocks.
- Header lockup: Patiun glyph + Cinzel "GREG KILMER" + "Web Development ·
  a Patiun LLC company"; glyph also marks the footer and store nav.
- Teal filled buttons with Midnight text; gold eyebrows; small links use a
  darker teal so they pass WCAG AA on Starlight.
- Favicons, app icons and web manifest from the GregKilmer.com brand package.
- docs/THEMING.md updated for the new palette and fonts.
