August 16, 2026 — Electrical Power merge (one dynamic section)
Path:
One grid, last two roles
- Removed Ohm / BTU / VD blocks and all field bridges (
injectOhmsUserValue, syncBridgeLock, duplicate V / I / P).
- New
PowerStep in electrical-calc.js: solver fields V, I, R, P, BTU; params length / phase / material; derived wire / drop / % / note.
- Last two typed solver fields are
active / previous. P ↔ BTU is an alias (3.412). Voltage starts empty (no fake 600 V anchor).
Exceeds safety
- Drop that cannot stay ≤ 3% at 4/0 marks length + drop % with
.is-unsafe: red “Exceeds safety” and strike-through.
- CSS in
styles.css / stylesdark.css only — no inline styles.
