feat: add bloom pulse animation to header logo, glitch text-only

- Counter-rotating rings now also pulse outward from center (inner→outer ripple)
- Use standalone `rotate`/`scale` CSS properties so animations don't conflict
- Glitch animation scoped to logo text span only, not the SVG
- Footer logo remains static (logo-static)
