/* Lake Erie Conditions
   ==========================================================================
   Theme derived from an actual Garmin GPSMAP chartplotter and the Navionics
   web app, not from an impression of one. Values below were sampled from
   Garmin's own screenshots:

     background        #060808   (device chrome, tab bar, panel ground)
     selected state    #47bdfe   (the blue bar under the active tab)
     data values       #ffffff   (large, plain white)
     caution           #ff9b00   (Navionics web app accent)

   What the real hardware does, and what this file therefore does:

   1. DATA IS WHITE. Not amber, not coloured. A small grey label sits above a
      large white number. Colour on a chartplotter means a state, never a
      reading.
   2. THE ACCENT MARKS SELECTION ONLY. Blue appears as a 3px bar under the
      active tab and nowhere else. It is never a fill, never a glow.
   3. PLAIN SANS, MIXED CASE. Garmin uses Roboto at normal letter spacing.
      No monospace, no uppercase headings, no letter-spacing. That combination
      is what made the previous attempt read as a synthwave terminal.
   4. FLAT. No gradients, no shadows, no glows, no rounded cards.
