Logo: adds a dedicated dark-mode variant (grey wordmark lightened to
near-white, green orbit untouched) and drops the white background chip
that was previously painted behind the logo in dark mode across Navbar,
AdminLayout and the admin Login page.
Cursor: the hover core goes back to brand green (with a white rim/glow
for contrast on green buttons) instead of white, per clarified feedback.
Homepage: new hero slogan "Home of pure Sound" (replacing "Audiophil aus
Prinzip" / "Audiophile by principle" in both languages), the "So
funktioniert's" / "How it works" three-step section is removed, and the
brand marquee is replaced with the client's actual supplier list (Ground
Zero Audio, Audison, Hertz, Helix, Brax, Gladen, Alpine, Pioneer,
Kenwood, JVC).
