+# Architecture
+
+Label Tools separates untrusted input from rendering:
+
+1. `labels/data.ts` uses toolbox helpers for bounded CSV/JSON parsing and the
+   browser cryptographic RNG for optional virtual fields.
+2. `labels/stocks.ts` stores canonical millimetre geometry and validates every
+   preset/custom grid before rendering.
+3. `labels/render.ts` maps scalar fields into three fixed layouts, escapes XML,
+   embeds validated local raster data, and places reviewed bwip-js output.
+4. `labels/export.ts` exports exact SVG pages, deterministic fflate ZIPs, or
+   locally rasterized pdf-lib documents.
+
+The React workbench retains the last valid data model after parse errors and
+limits interactive preview to the first 12 pages. Complete SVG export remains
+available for all bounded rows. The shared toolbox shell owns theme and portal
+navigation; all app URLs are relative for nested deployment.
