/* ============================================================================
   WORKSPACE OVERVIEW — QUIET INSTRUMENTS
   Redesigned KPI tiles. The old "huge number inside an SVG ring" composition
   broke at any value ≥ 2 digits (the 11 hit the stroke; 86.0% overflowed
   entirely). New layout separates the readout from the indicator:

       ┌──────────────────────────────────┐
       │ ⬤ DESIGNS                        │  ← mono eyebrow with status dot
       │                                  │
       │ 11                               │  ← big Plex Serif numeral, top-left
       │                                  │
       │ analyses run                     │  ← subtitle
       │ ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ │  ← 3 px progress bar at bottom edge
       └──────────────────────────────────┘

   The bar is driven by a `--fill` CSS variable set on the tile element by
   setRingFill() in app.js, so the numeric readout and the indicator can
   never overlap regardless of the value. The SVG ring is hidden — kept in
   the DOM for backwards compatibility but never painted.
