Turn a PNG (or JPG/WebP) into SVG two ways: Embedded Vector Wrapper (full-size base64 image in an SVG shell — scales without re-saving, not true vectors) or Silhouette Path Trace (black-only 1px-rect tracing of dark pixels on a capped 250px thumbnail). Downloads as traced_vector.svg — local Canvas work, no uploads.
By your percentages: grams = calories × share ÷ 4 (protein/carbs) or ÷ 9 (fat), and shares must total 100 (±1) or no result shows. Defaults (2000 kcal at 30/40/30) give 150g protein, 200g carbs, 67g fat.
Same protein, different totals: deficit trims carbs/fats first; surplus adds carbs around training. Protein stays high in both.
No — weekly averages beat daily perfection. Protein within 10g, calories within 100: consistency over precision.
