/* ==========================================================================
   TITANOM.AI — DATA VISUALISATION
   Donut, radar, grouped bars, gauge and the animated level climb.
   All inline SVG or plain HTML. No chart library, no dependencies.

   COLOUR RULES — do not improvise on these.
   ---------------------------------------------------------------------
   Two categorical series maximum. The pair below was validated against
   this site's dark surface (#080909) for lightness band, chroma floor,
   colour-blind separation, normal-vision separation and contrast:

     Series A (Titanom / after)   #11A3A3
     Series B (typical / before)  #B08A10

   Anything showing parts of a whole or magnitude uses the SEQUENTIAL TEAL
   RAMP instead, ordered light to dark by size, never a set of random hues.
   Never add a third and fourth hue to make a pie look colourful: fold the
   tail into "Everything else".

   Bright brand tokens (--teal-bright, --gold) are for glow, strokes and
   labels. The validated pair above is for the data marks themselves.
