Lab Report (Certificate of Analysis) — rendered output
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.

<h2 class="sh">Interpretation and recommendation</h2>
<div class="prose measure82">
<p>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.</p>
<p>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 Sterilizer 3 need not be withdrawn from service on this result alone; the resample should be treated as urgent.</p>
