  /* =====================================================================
     LC-005 T-17 — Confidence heatmap
     - Per-word ASR confidence paints a thin underline under the lyric word.
     - Per-chord ACE confidence paints a thin bar under the chord label.
     - Colors are set inline via CSS custom properties (--asr-hm-color /
       --chord-hm-color) because confidence_to_color() emits a continuous
       gradient (~380 distinct hex values). Enumerating each hex as a CSS
       attribute selector wouldn't scale; CSS attr(color) is Level-5 spec
       with near-zero browser support as of 2026.
     - body.heatmap-off suppresses both in one place for clean toggle.
     - Responsive: lane uses inline padding rather than a separate stacked
       row so mobile layout is untouched.
