**Score Comparison Plot:**

The following plot shows how this terminal's scores compare to all other terminals tested.

.. figure:: ../_static/plots/contour_scores_scaled.png
   :align: center
   :width: 800px

   Scaled scores comparison across all metrics (normalized 0-100%)

**Final Scaled Score Calculation:**

- Raw Final Score: 74.09%
  (weighted average: WIDE + NARROW + ZWJ + LANG + VS16 + 0.33 * SRI + 0.33 * SFZ + RI + CAP + 0.5 * GFX + 0.5 * RSC)
  the categorized 'average' absolute support level of this terminal.

  .. note::

     RSC (Resources) is a composite CPU, memory, and runtime score.
     RSC is weighted at 0.5 (half as powerful as other metrics).
     FEAT (Features) is the fraction of notable features supported.
     GFX (Graphics) scores 100% for modern protocols (iTerm2, Kitty),
     50% for legacy only (Sixel, ReGIS), 0% for none.

- Final Scaled Score: 65.8%
  (normalized across all terminals tested).

The ``XTGETTCAP`` sequence (``DCS + q Pt ST``) allows applications to query
terminfo capabilities directly from the terminal emulator, rather than relying
on the system terminfo database.
