/* landing.css — marketing/showcase page for justlayers.com root.
   Redesigned 2026-09-10 toward a cleaner, more restrained, "Apple-like"
   dark aesthetic (explicit user request: "very black and flashy... should
   be clean and modern" — see ideas-and-plans/PLANS.md for the full
   reasoning behind the choices below). Still the same dark palette as
   before — this isn't a light-mode redesign, and it still matches the
   app's general dark, nautical feel — but the base tones are now neutral
   rather than blue-tinted, the teal accent is desaturated and used more
   sparingly (that near-neon teal against near-black was doing most of the
   "flashy" work), borders are softer, and there's more breathing room
   between elements. Pulls the app's shared visual language (Space Grotesk
   + Inter, soft corners) but this file has its own tokens/layout — it's
   not a copy of app/style.css, and doesn't touch it. */

:root {
  /* Neutral near-black rather than the previous blue-black (#0A0E14) — a
     cooler blue-black reads more like a glowing screen; a slightly warmer,
     more neutral gray-black reads calmer and more considered, closer to
     how Apple's own dark surfaces are toned. */

     contributor to "flashy." Kept clearly teal (still the brand color),
     just calmer, and used more sparingly below (primary CTA, focus/hover
     states, a couple of small pills) rather than tinting every icon. */
