/* Keythentic site — hand-written CSS, no build step, nothing loaded from anyone else.

   Design system: the Android app's default theme, Midnight.
     page    near-black #0B0D10 with #15181D panels and hairline borders; no gradients
     accent  lime #C6F432 for fills (buttons, icon glyphs, the countdown), with ink text on it
     status  green = stays on device / safe, amber = leaves the phone / caution, red = danger
   Type: Space Grotesk, with JetBrains Mono for codes (both OFL, self-hosted), as in the app.
   Dark by default, like Midnight; the header toggle switches to a light version. The legacy token
   names (blue, grad, pine, mint, brass, paper, sand) are kept so every rule keeps working; their
   values are Midnight's. --blue is the accent FILL and --blue-ink the accent TEXT tier. */
