The PDF at /sample-report.pdf is a derivative work. It is generated from a
public IFC reference model and renders quantity takeoff data extracted from
that model.

Modifications
-------------
The original IFC is unchanged on disk. The PDF in this directory is a
*derivative* work generated by ifcreport.app's takeoff renderer
(lib/pdf.tsx). It summarises element counts, quantities, materials, and
per-storey breakdowns from the source model.

In addition, two label fields are translated from Dutch to English in
memory before rendering, so the PDF is readable to an English-speaking
marketing audience:

  - The IFCPROJECT name is rendered as
      "Schependomlaan apartment building (10 units)"
    instead of the original "10 Appartementen Schependomlaan".
  - The seven IFCBUILDINGSTOREY names are translated as follows:
      "-1 fundering"          → "-1 foundation"
      "00 begane grond"       → "00 ground floor"
      "01 eerste verdieping"  → "01 first floor"
      "02 tweede verdieping"  → "02 second floor"
      "03 derde verdieping"   → "03 third floor"
      "04 dak"                → "04 roof"

No quantitative data from the source is altered. Material names, IFC
class names, element counts, volumes, areas, and storey elevations are
all passed through unchanged. The translation map lives in
scripts/build-sample-report.tsx for transparency.
