A dedicated /labs page hosts manual entry and a per-analyte view: the
four essentials (biomarker, value, unit, date) stay visible, the
reference range, panel grouping and note sit under an optional section.
Results group by analyte with a small inline trend once an analyte has
two or more readings. The reference-range badge is deliberately neutral
and calm — an out-of-range value reads as a quiet directional marker, not
an alarming red.
Adds the labs section toggle to the health-record export panel, the /labs
nav entries, the /api/labs OpenAPI routes, and the labs copy across all
six locales.
