/* Pinglight — marketing site.

   Type is the system monospace stack throughout: the app itself is set in the
   system monospaced face, and shipping zero font files is the same posture as
   shipping zero third-party bytes. No Google Fonts link anywhere; the CSP is
   `font-src 'self'` and nothing ever requests a font.

   Two sections:
     1. LANDING PAGE (body.lp) — the dark phosphor-radar artboard.
     2. LEGAL PAGES (body.legal) — privacy.html / terms.html, same palette,
        quieter chrome.

   Palette = the app's PinglightTheme (RootView.swift), converted to sRGB hex:
     background #030907   panel #07130F   phosphor #4DFF99   dim #598C73
     grid = phosphor at 16%
   Category accents (Models.swift): amber #FF9E40 (tracker), violet #D973F2
   (glasses), yellow #F2D959 (beacon), blue #66BFF2 (wearable). */
