/* ───────────────────────────────────────────────────────────────
   Helios — website, one screen, on the Helios design system.

   Everything here is a var() from helios-ds/tokens — this file lays
   the page out, the system decides how it looks. The rules that came
   with the tokens:

     · Sun yellow FILLS shapes; anything READ is --amber-ink or darker.
     · Everything the page SAYS is Lora; everything it LABELS is Outfit.
     · Sentence case everywhere. HELIOS is the only all-caps text.
     · Nothing interactive under 17px; often-pressed things clear 56px.
     · Ember means risk. It is never decoration.
     · Entrances/exits ease-out, movement ease-in-out. No ease-in.

   One page, no scrolling: the screen is a header / main / footer
   column pinned to the viewport. On a phone-sized window it gives up
   the pin and scrolls — cutting content off would be worse.
