/* ─────────────────────────────────────────────────────────────────────────────
   Palette
   Rooted in the consulting site's deep green-teal so the two read as one
   company. The previous scheme was navy + cyan, which is the single most
   common machine-generated look there is; the brand hue is what makes it not
   that. The dark theme is therefore green-black, NOT navy.

   Light is the default and is NOT overridden by the OS preference. That is a
   deliberate departure from the usual advice: the consulting site is light-only,
   so a visitor whose OS is dark would otherwise land on a wall of dark green and
   see what looks like a different company. Light is the shared identity; dark is
   opt-in through the toggle, which sets data-theme="dark" on <html>.
   To follow the OS instead, wrap the dark block in
   @media (prefers-color-scheme: dark) and target :root:not([data-theme="light"]).

   Clinical status colours (critical/unstable/tenuous/improving/stable and the
   vitals) are declared per theme rather than inherited. They are a patient
   signal, not decoration: the red that reads "critical" on white is not the red
   that reads "critical" on green-black, and neither may be confused with the
   teal used for brand and interaction.
