/* ---- Custom cursor (targeting-reticle / HUD motif) ----------------------
   A precision targeting reticle: a small center node + a thin ring with
   N/E/S/W ticks that tracks the pointer exactly (no lag — it should feel
   like a control-system crosshair: "control latency, control inference").
   It locks on (brightens + glows) over interactive elements, dims on press,
   and becomes a slim I-beam over text fields. Progressive enhancement: JS
   adds .has-cursor only on a fine pointer (mouse); the native cursor stays
   on touch / when JS is off.                                                */

/* ---- SLA "Service guarantees" — an interactive 3D orbital carousel --------
   The 4 cards orbit a glowing core along a tilted ellipse, spinning a full
   360° continuously. Drag to spin (with momentum), hover to pause, click a
   card to glide it to the front (front = brightest/largest/closest). main.js
   `slaOrbit()` drives it with requestAnimationFrame, writing the finished
   transform/opacity/scale per frame on each .sla-slot — so there is NO CSS
   var-math (which silently fails in this engine). The default layout (no JS,
   mobile, or reduced-motion) is a plain readable vertical list: the JS only
   adds `.is-orbit` when it is safe to animate (wide viewport, motion OK).    */

/* ===== Stat band — five metrics, one row on desktop =====================
   The precompiled Tailwind build ships no `grid-cols-5`, so this band owns
   its own grid + responsive number sizing here. Two columns on small
   screens; five across from 900px up. The big numbers scale with the
   viewport (and never wrap) so the widest one — "12 months" — always fits
   its column. */
