    "format": "annotated-photo",
    "reason": "A marked-up wall photo helps settle height, spacing and alignment around furniture.",
    "brief": "Overlay the proposed shelf edges, bracket positions and key clearances on the supplied wall photo; do not imply hidden services are known."

  "materials": [
    "Shelf boards rated for the intended load",
    "Compatible brackets or concealed shelf hardware",

    "Small protective pads or finish repair material where needed"

  "tools": [
    "Tape measure, pencil and long spirit level",
    "Cable, pipe and stud detector used as an aid, not proof",
    "Drill-driver, bits and dust collection suited to the confirmed wall",
    "Hand tools specified by the shelf and fixing makers"
  ],
  "preparation": [
    "Decide what the shelves will hold and check the hardware's rated load.",
    "Identify the wall construction rather than choosing a fixing by appearance.",
    "Check likely pipe and cable routes and inspect both sides of the wall where possible.",
    "Tape the shelf outline to the wall and confirm headroom, doors and furniture clearances."

  "safety": [
    "A detector cannot guarantee a drilling point is clear; stop where services or construction are uncertain.",
    "Heavy, cantilevered or child-accessible shelving needs an appropriate structural fixing and anti-pull-out design.",
    "Wear the protection specified for the wall material and control drilling dust."
