/* GoalKick — goalkick.co

   The palette is the game's own menu palette (godot/scripts/menu.gd):

       bg            #050d08   near-black green, the whole page sits on this
       accent        #3eb55c   phosphor green
       accent-bright #57db75   phosphor green, lit
       ink           #dfeee4   body text
       muted         #8fae9b   secondary text (still AA against bg)

   No build step, no framework, no fonts to fetch. One stylesheet, one page.
   Night stadium: near-black green, thin dim-green hairlines, uppercase
   letter-spaced headings — the game's own menu language, not a generic
   dark theme. */
