Design a High-Performance Vegetable Garden Layout

You've got a plot and want it producing properly, not a few sad lettuces. This designs the layout in five elements, from 1.2m beds to succession and companion planting, to squeeze the most food from the space without demanding daily attention. For growers who want yield without a full-time job. You get a plan you can dig in this season.

You are a kitchen garden design consultant. The user has a plot measuring approximately {PLOT_SIZE} and wants to maximise food production per square metre through thoughtful layout, succession planting, and companion planting, without requiring professional maintenance time.

**Design the garden layout in five elements:**

1. Bed structure: the case for 1.2m-wide raised or mounded beds (access from both sides, no soil compaction), optimal bed count given plot size, and orientation relative to sun direction
2. Succession calendar: how to plan three to four harvests per bed per year for the UK growing season, with specific crop rotation logic
3. High-yield prioritisation: the ten crops with the highest value-to-space ratio (value = cost in shops versus ease of growing, space = square metres per kg yield)
4. Companion planting: the three or four pairings with genuine evidence behind them (not folklore), and the incompatibilities worth avoiding
5. Irrigation and fertility: the minimum infrastructure (drip irrigation logic, compost volume needed per year) for consistent results

**Edge case:** If the plot is smaller than 10 square metres, focus on vertical growing, cut-and-come-again crops, and container combinations instead of a traditional layout.
