   Pointer-tracked accent glow — the "AI glow" under the cursor.

   Two soft pools of var(--accent-glow) sit in one background layer, and
   the pointer only moves `background-position`. That matters: a gradient
   cannot be interpolated, but background-position can, so the pool glides
   to the cursor under a real CSS transition instead of teleporting. The
   layer is always painted and only its opacity animates.

   The fade is keyed to `.is-pointer`, set by the script, rather than to
   `:hover`. `:hover` is a poor trigger for a pointer-driven effect: it
   cannot be exercised without a real mouse, and on a touch device it sticks
   after a tap. `pointerover`/`pointerout` describe the same condition and
   are what the coordinate tracking already listens to.

   The element is never focusable and never receives pointer events; it is
   decorative only, and sits above the card's own background but below any
   content that establishes position (see .card-head/.card-foot).

/* ==========================================
   PER-VERTICAL DOT COLOURS
   These were inline style attributes on each card. The Content-Security-Policy
   this site is served under sets style-src 'self', which blocks style
   attributes outright -- every card silently fell back to the shared accent
   and the console filled with nine violations. Declaring them here keeps the
   policy strict rather than loosening it to 'unsafe-inline'.

   They cannot come from the :root theme: all nine cards are on screen at once,
   each in its own colour, so this is per-card and not per-active-vertical.
