    ============================================================
    BASIN DIAGRAM (ps-basin-diagram)
    ============================================================
    Coordinate system: SVG viewBox is 520 (wide) × 430 (tall).
    Origin (0,0) is top-left.  +x goes right.  +y goes DOWN.
    Bigger y = lower on screen.

    X-LANES (all viewBox units, edit any of these to shift a column):
      x ≈   5..75   left input column (inlet number input)
      x =  80       inlet unit "m"
      x = 135       inlet text labels (right-aligned, anchor at x)
      x = 140..200  inlet arrow (line + arrow head into tank)
      x = 200..320  tank body (rect.x=200 width=120) — interior 201..319
      x = 195/325   threshold tick lines (extend 5 px outside tank)
      x = 260       mid-tank zone labels (centered)
      x = 320..360  outlet arrow
      x = 330       right-side label column ("overflowLevel", "Outlet", …)
      x = 365       outlet sub-text column
      x = 425..495  right input column (foreignObject inputs, width=70)
      x = 500       right unit column ("m", "m³")

    Y-COORDINATES:
      y =  40       tank rim (basinHeight line)
      y = 380       tank floor / datum
      y = 410       ordering warning ribbon
      y =  19,44    "basin volume" / "basinHeight" labels (static)
      Threshold rows (overflowLevel, highVolumeSafetyLevel, inflowLevelGuide,
        dryRunLevel, outflowLevel, basinHeight tick) get y assigned
        DYNAMICALLY by the redraw() function around line 250-340 below.
        Their input row may be NUDGED off ideal-y to avoid overlap; a leader
        line (ps-leader-*) is then drawn between threshold y and input y.
      Zone-label rows (ps-zone-*) get y assigned dynamically to the midpoint
        between adjacent thresholds; they hide if the gap is too small.

    HOW TO NUDGE OVERLAPPING LABELS:
      - For STATIC y values (hardcoded below): edit the inline y attribute.
      - For DYNAMIC y values: search redraw() for the element id and adjust
        the layout math (e.g. NUDGE_PX or the threshold-stack ordering).
      - For x: every label column above can be shifted by editing the inline
        x attribute on the relevant <text>/<line>/<foreignObject>.

    Note: dynamic line/label positioning lives in oneditprepare → redraw()
    further up in this file. Changing only the inline y here will be
    overridden on first redraw for any element whose id appears in redraw().

      ============================================================
      LEVEL-BASED MODE PREVIEW (ps-levelbased-mode-diagram)
      ============================================================
      Coordinate system: SVG viewBox is 430 (wide) × 185 (tall).
      Origin (0,0) top-left.  +x right.  +y DOWN (so y=24 is HIGH on screen,
      y=158 is at the baseline).

      X-AXIS (level, in viewBox px) — controlled by redrawModeDiagram() in
        the oneditprepare script above.  The function maps the user's
        startLevel/inflowLevel/maxLevel/shiftLevel onto the px window
        x0=52 (left axis) → x1=390 (right end of plot).
        DO NOT hardcode x for ps-mode-line-* / ps-mode-label-*; they're
        rewritten on every input change.

      Y-AXIS (process demand %):
        y=24    100%   (top of plot)
        y=140   0%     (baseline / x-axis)
        y=160   OFF baseline (pink dashed)
        y=180   axis labels under the plot ("dry run","start","inlet","max","overflow","shift")
        y=205   legend captions (one row, BELOW axis labels — moved here to stop
                colliding with the title row at y=14)
        y=14    curve-type title only ("linear curve" / "log curve"), centered.

      WHAT IS STATIC vs DYNAMIC:
        STATIC (edit inline below): viewBox bounds, axis lines, "0%"/"100%"
          tick labels, in-plot caption x/y, axis-label y=176.
        DYNAMIC (edit in JS): every ps-mode-line-*, ps-mode-label-* x;
          ps-mode-curve-up/down points; visibility of shift elements.

      HOW TO NUDGE OVERLAPPING TEXT:
        - Move the curve-type caption: edit the x="220" y="18" on
          #ps-mode-curve-label.
        - Move axis labels (start/inlet/max/shift) UP or DOWN: edit y="176".
          (To move them left/right relative to the line, edit redrawModeDiagram
          in the script — the x is set there.)
        - Move the legend captions: edit x="280" y="54" / y="72" on
          #ps-mode-curve-up-label / #ps-mode-curve-down-label.
        - To resize the plot box, change viewBox + the x0/x1/y0/y1 constants
          in redrawModeDiagram() to match.
