/* =====================================================================
   FPL Analyzer — Home / Landing redesign
   Layout & component language adapted from the "Mercury" style reference
   (DESIGN.md), re-themed to the FPL Analyzer purple/green palette.

   Mercury token  ->  FPL mapping
   ----------------------------------------------------------------
   Deep Space   #171721  -> --pl-purple3  #1d0024   (page abyss)
   Midnight     #1e1e2a  -> --pl-purple2  #2a0032   (surface)
   Graphite     #272735  -> --pl-card2    #3c0845   (interactive)
   Mercury Blue #5266eb  -> --pl-green    #00ff87   (single accent / CTA)
   Ghost Blue   #cdddff  -> rgba(0,255,135,.14)     (secondary surface)
   Lead         #70707d  -> rgba(192,168,200,.16)   (borders / dividers)
   Starlight    #ededf3  -> #ffffff                 (primary text)
   Silver       #c3c3cc  -> --text-secondary        (secondary text)

   All rules are scoped under #viewLanding so the rest of the app is
   untouched. Density is "spacious": 80px+ gaps between sections,
   light-weight large display headlines, pill buttons, flat surfaces.
