Bold vector SVG design: minimal, chic composition that blends an abstract mark logo with a stethoscope. Square 1:1, viewBox="0 0 512 512". Centered icon with a safe margin of about 10–12% from each edge; visually balanced without perfect symmetry. The core motif should resemble a soft-rounded frame or simple pictogram; a stethoscope tubing curls around it to unify both elements into one cohesive form. Chestpiece placed as a small accent in the bottom-right corner. Style: Flat / Outline+Soft with rounded corners; uniform stroke width 8–10; stroke-linecap: round; stroke-linejoin: round; no textures, shadows, gradients, or 3D effects. Details kept legible at small sizes (24px, 48px). Recolor-friendly: all colors defined via CSS variables --primary, --secondary, --accent, --bg; all strokes/fills reference these vars. No text; only paths/shapes. SVG structure: <g id="mark">...</g> and <g id="stethoscope">...</g>. Background transparent. Ready for recoloring and scalable rendering.

The image shows a black and white icon of a stethoscope on a white background. The icon is a representation of a doctor's stethoscopes, which are used to measure the size of a patient's teeth.
