Drop-in, no dependencies. ## The rules that matter most - The name is always ProductLed. Capital P, capital L, one word, no space, no hyphen. - Yellow is #F3CA07 and it is rationed. One accent per viewport. Never a page fill, never a resting button. - Text on yellow is always #08090A. Never white. - Primary buttons are white (#F7F8F8) with #08090A text, and flip to yellow on hover. Never a pill. - Geist for everything, Geist Mono for labels and numbers. Display never exceeds weight 500. - Text is #F7F8F8 or #8A8F98. The darker greys (#62666D and below) never carry a label or body copy. - No em dashes, no emoji, no superlatives. Sentence case everywhere. - The mark is the Market Ascent pyramid. Its summit is always yellow. Never rotate, recolor, stretch or crop it. ## Contact - Brand questions: hello@productled.com
