/* The landing page: ONE SCREEN that never scrolls. The words on the left, and on the right
   a glass "stage" holding a guided tour of the planner: a rail of seven steps, each one a
   working piece of the real thing (js/showcase.js, js/landing-globe.js), ticked off as the
   visitor uses it.

   Built from design/brand/Redesign/: the liquid-glass hero (split layout, glass panels, a
   hover-reactive icon grid, a stacked deck of cards) and Design.md (Inter + JetBrains Mono,
   8px control radius, the light palette).

   Glass = a translucent fill + backdrop blur + a faint noise grain + a gradient hairline.
   The blur sits on a pseudo-element BEHIND the content, never on the element holding the
   text, and nothing uses 3D transforms: those are what made the old cards look soft. */

/* ============================== THEMES ==============================
   Two: light and dark. html[data-theme] always holds the resolved one: set before the first
   paint by the inline script in index.html (the visitor's saved choice, else the device's
   setting) and switched by the sun/moon button in the header.

   LIGHT is Design.md: a white ground, the orange #FD6703 as the main button (with black text,
   7:1) and pink and lavender as the supporting glow colours. Orange TEXT uses a deeper shade,
   because #FD6703 only reaches 2.9:1 on white.
   DARK is the reference HTML's own look: black, white glass, sky/indigo/emerald glows. */
