No third hue, no gradient, no grain.", "set_rule": "across a set of four, give each poster a distinct colour family — never two blues" }, "step_system": { "form": "a white channel with a hard stepped edge, like pixel stairs, running vertically through the frame and bleeding off top and bottom", "module": "step rise and run are ONE fixed unit across the whole set — roughly 1/16 of the poster width; never resize per poster", "count_rule": "one channel by default; split into two stepped blocks only when the craft has two simultaneous points of impact (cymbal and snare), one block per point", "hot_rule": "whatever falls inside the channel switches to the hot colour — and the channel must be positioned so it lands on the part of the body or tool doing the work right now" }, "typography": { "headline": "3–4 words in a clean neo-grotesque, sentence case — capital first letter only, everything else lowercase; black; 2–3 lines; top of frame", "dates": "day numbers stacked vertically as large black numerals, month and year in smaller caps beneath; ONE fixed position across the set — right side, aligned to the headline's vertical axis", "footer": "one line of small bold caps bottom-left: the event name, a slash, the format (OPEN PRACTICE / PROCESS LIVE / LIVE ROOMS / OPEN SESSIONS)" }, "photography": { "subject": "one practitioner at the peak of an action — mid-dive, mid-stride, mid-gather, mid-strike; never posed, never facing the lens", "setting": "the real venue stays visible and duotoned — pool tiles and board, track lanes and floodlights, studio bench and furnace, drum kit and cymbals", "crop": "full body where the action needs it, waist-up where the tool does" }, "design_rules": [ "headlines follow one grammar: [noun] in [state] — Bodies in blue, Matter in motion, Sound in the making", "no two posters in a set may repeat a word", "the channel is the identity — keep it geometric, never soft or torn", "everything printed sits on the flat field; nothing overlaps the photograph except the channel" ], "swap_variables": { "discipline": "diving / sprinting / glassblowing / percussion", "headline": "Bodies in blue / City in stride / Matter in motion / Sound in the making", "colour_pair": "cobalt+red / warm orange+blue / turquoise+orange / acid yellow+violet", "hot_zone": "torso entering the water / driving leg / molten gather on the pipe / cymbal and snare", "footer": "AQUATIC MOTION · OPEN PRACTICE / URBAN TRACK MEET · OPEN SESSIONS / GLASS STUDIO DAYS · PROCESS LIVE / PERCUSSION WEEKEND · LIVE ROOMS" } }
