/* ---------------------------------------------------------------------
   Optic Gecko site — shared by the landing page and the legal pages.

   Structural language borrowed from webgecko.au (fixed nav, full-height
   hero, ~90px section rhythm, Oswald display over Inter body, uppercase
   letterspaced buttons, scroll-reveal) but the palette is the app's own
   Meridian/Understory greens rather than webgecko's near-black and orange —
   this is the product's site, so it should look like the product.

   Every path in here and in the pages is RELATIVE. The site is served from a
   subpath (webgecko.au/optic-gecko/), so a leading slash would resolve to
   the parent domain root and 404.
