/* ---------------------------------------------------------------
   Logo wordmark font — pick ONE (comment out the others).
   All options are preloaded in index.html, so switching is instant.
   Vibe: professional + tech, designed but not flashy.
     1. Space Grotesk — geometric, modern, subtle techy character  (recommended)
     2. Sora          — clean geometric, understated & corporate-tech
     3. Chakra Petch  — squared/engineered, stronger "tech" feel
     4. Michroma      — wide, futuristic, minimal (a touch more sci-fi)
     5. JetBrains Mono— monospace, developer/terminal vibe
     6. Inter         — the current neutral default
   Tip: Chakra Petch / Michroma read better with a little more
   letter-spacing (e.g. 0.01em); Space Grotesk / Sora with -0.02em.
