   E-ink display stylesheet — TRMNL dashboard server
   ═══════════════════════════════════════════════════════════════════════════

   Hard rules for 1-bit e-ink:
   · #000 and #fff ONLY — no grey, no opacity, no rgba()
   · Minimum font size: 14px for anything that must be read
   · Sans-serif for text ≤ 20px (thicker strokes survive thresholding)
   · Serif only for large display numbers (≥ 40px) where strokes are thick
   · No dashed/dotted borders — render as uneven dots on e-ink
   · No box-shadow, text-shadow, or filter
   · No opacity — use solid colors instead
