Looks like a friend's post, reads like an ad only after the scroll has already stopped.
Vertical 4:5 static built to pass as an organic story post. The photo: a candid phone-shot close-up of [PRODUCT IN CONTEXT — e.g. "two Renva citrus electrolyte drink sticks lying on green gym turf, propped against a scuffed blue water bottle"], taken from above at a casual angle in harsh direct midday sun — deep hard shadows raking across the ground, saturated true-to-life color, visible grit and texture in the surface, zero studio styling, framing slightly imperfect like a friend snapped it mid-workout. One packet leans upright and fully legible; a second lies half-turned behind it. Darken the top of frame with a subtle gradient so overlay text reads cleanly. Across the upper fifth, native creator-style overlay text in tall condensed bold caps on two centered lines, verbatim: "[OVERLAY — e.g. "RECOVERY TO LAST" on line one, "EVERY REP" on line two]" — with the single benefit keyword "[KEYWORD — e.g. "RECOVERY"]" colored in the brand hue and every other word white. The type must look typed into a story app, not art-directed. All text crisp and unwarped, correct spelling. No logo lockups, no borders, no badges, no watermark, no hands or faces, no studio lighting.
