The certificate of analysis: results against reference ranges with exactly one flagged out-of-range value — accent, bold, set larger, and captioned "Exceeds", never colour alone. Change the sample block and the results rows in `data.json` first; keep at most one flagged row per the accent policy. Caveat: spec limits are written in the set's "max" idiom ("1.3 max"), not "≤" — the bundled Unicode fallback font does not cover the math-operator block, and the engine reports any such uncovered glyph as a render defect; register a font containing it if you need the symbol form.
**Engine features exercised:** solid accent tab via flex shrink-wrap, per-cell flagged styling in a data table, three-slot signature row, single-page fill.

Seven of eight analytes are within the reference ranges specified for sterilizer feed water at this facility. The heterotrophic plate count of 138 CFU/mL exceeds the action limit of 100; the duplicate returned 129, so the result is reliable rather than a plating artefact. Endotoxin remains well within limit, consistent with biofilm in the distribution loop rather than a breach of the membrane.
We recommend sanitisation of the loop downstream of the polish cartridge, replacement of the point-of-use filter at sterilizer 3, and resampling at two points after seventy-two hours. Sterilizer 3 need not be withdrawn from service on this result alone; the resample should be treated as urgent.
