Seatwise Seating Planner

Use this when the user wants a seating chart or seating plan: a classroom seating chart for students (rows, pairs or groups of 4; keep two students apart; seat some students near the front; mixed groups; a new random seating chart each week that avoids last week's neighbours) or a wedding, party or banquet seating chart (round or long tables of N, keep couples and households together, keep two guests apart, head table, kids table). Accepts typed names or an uploaded roster or guest list (CSV/Excel). It checks each hard rule and reports any conflict, naming the rules that cannot all hold together. Returns the chart, a soft-preference score, and links to a printable PDF, place cards and Excel. Same seed gives the same chart; change seed to reshuffle. Does not seat stadiums, theaters or airplanes, and does not store rosters.

Use this when the user already has a seating chart (typed rows or tables, or a file with Name and Table columns) and wants to check it against rules: who must be kept apart, kept together, needs a front seat, households together, head table and kids table, table capacities. Returns each broken rule with the people involved, the soft-preference score, and the same printable PDF, place cards and Excel for that chart. Does not move anyone; to make a new chart use generate_seating_chart. Not for stadium or airline seat maps.
