12-Panel Yoga Flow Instruction Diagram

Create a 12-panel yoga instruction diagram in a clean 4-column by 3-row grid. Style: black-and-white / soft grayscale instructional poster, off-white background, thin black panel borders, bold uppercase titles, black rounded number badges, simple dotted or curved motion arrows, and short coaching captions. Use one consistent female yoga model across all panels: athletic build, long wavy hair, fitted sports bra and leggings, barefoot, realistic photo-illustration style, neutral studio background. Show a classic vinyasa flow from Mountain Pose to Downward-Facing Dog. Focus less on overly technical pose detail and more on the feeling of a smooth flowing sequence, with clear movement, breath, and transitions from one step to the next. Each panel should clearly show the motion step and how it transitions into the next pose. Use arrows to show direction of movement. Keep the captions short and simple, describing the action, breath, or flow cue in a natural way. Make all 12 panels exactly the same size, evenly aligned, highly readable, and visually consistent. No color. No extra text.
