+/**
+ * DrillTeeth
+ *
+ * Abstract, minimalist section divider inspired by HDD bore paths.
+ * Not literal teeth — instead, a subtle organic wave that hints at
+ * earth strata displaced by subsurface drilling.
+ *
+ * Two gentle asymmetric curves create a refined, modern transition
+ * between sections. Think Stripe/Linear, not construction site.
+ *
+ * Usage: Place inside a section with `relative overflow-hidden`.
+ * The SVG renders outside the box via translate, creating overlap.
