Splash: icon-only corner buttons on mobile, click-to-enter wave

- Mobile: corner nav buttons become icon-only (Portfolio/Apps/Services/About)
  with aria-labels; subheader hidden on mobile so nothing overlaps the logo.
- More ambient motion: logo float plus a second counter-rotating glow ring.
- Clicking the logo (or Explore) triggers a Cherenkov wave (wash + expanding
  rings) before entering; reduced-motion enters instantly.
- Beveled glass buttons.
