🟠 HIGH (security): ExportButtons.escapeCsvCell now prefixes cells starting
with =/+/-/@/tab/CR with a leading apostrophe (OWASP CWE-1236). Prevents
Excel/Calc/Sheets from evaluating attacker-controllable strings (egrn.address,
cad_num) as formulas (=cmd|... / =HYPERLINK / DDE).
🟡 MEDIUM: buildFallbackEgrn now returns area_m2: NaN instead of 0; KPI 'Площадь'
and EgrnPropertyTable 'Площадь' row both gate on Number.isFinite + >0, rendering
'—' consistently when EGRN absent (previously asymmetric: KPI '—' / table '0 м²').
🟢 LOW: scoreVerdict collapsed dead branch (both >=80 and >=65 returned same
ПОДХОДИТ label). MiniMap toSiteMapData narrows source via explicit ternary
instead of unchecked 'as' cast.
