Pairs with the generalFunctions curve-file rewrite — all supplier
curves now share one X-axis: specific air flux through the membrane,
Nm³/(h·m² membrane). specificClass._calcOtrPressure computes the flux
from the existing n_flow and i_n_elements plus a new i_membrane_area
field, and queries the OTR / DWP curves at that flux instead of at
flow per element.
i_membrane_area resolution (precedence top-down):
1. config.diffuser.membraneAreaPerElement (new optional override)
2. specs._meta.membraneArea_m2_per_element (curve-file source of truth)
3. 0.18 m² (Jäger TD-65 / GVA placeholder)
_loadSpecs now preserves the curve's full _meta block so the area
metadata reaches configure(). Output schema gains oFluxPerM2 alongside
the existing oFlowElement (kept for user-readability — both numbers
are useful on a dashboard).
_checkLimits compares specific flux against the curve's minX / maxX
(also in canonical units now), so warning / alarm thresholds remain
self-consistent.
8/8 tests pass. Verified across all 5 suppliers (gva-elastox-r,
jaeger-jetflex, aerostrip-phoenix, pik300, prk300) that the resolved
flux + SSOTR + DWP numbers match hand-computed expectations.

_loadSpecs() now calls loadCurve(model) instead of returning a hardcoded
literal. Default model 'gva-elastox-r' keeps the legacy GVA numbers; the
editor cascade (supplier → type → model → unit) lets users pick Jäger,
Aerostrip, or PIK/PRK once those curve files land in generalFunctions.
Editor changes:
- diffuser.js serves /diffuser/menu.js + /diffuser/configData.js
- diffuser.html loads the shared MenuManager scripts, includes
asset-fields-placeholder + logger-fields-placeholder, and runs the
shared init/save lifecycle.
- Density field re-labelled "Bottom coverage [%]" — semantics were
always meant to be % surface-area coverage; "elements per m²" was a
prior mis-conversion. Default flipped 2.4 → 15 (typical fine-bubble).
- New defaults: model, unit, assetTagNumber.
specificClass:
- buildDomainConfig now forwards uiConfig.model/unit/assetTagNumber
under config.asset.* so _loadSpecs can resolve it.
- _loadSpecs walks config.asset.model || config.model || DEFAULT, falls
through to GVA on a missing curve file (with a clear error if neither
resolves to a usable otr_curve + p_curve).
All 8 unit + structure tests pass.

Refactor of diffuser to use the platform infrastructure (BaseDomain, BaseNodeAdapter,
ChildRouter, commandRegistry, statusBadge). Extracts concerns into
focused modules per .claude/refactor/MODULE_SPLIT.md generic template.
Tests stay green; CONTRACT.md generated; legacy aliases preserved.
