/**
 * Calculate welding heat input, cooling time, and preheating requirements.
 * Implements AWS D1.1, EN 1011, and Yurioka methodologies.
 *
 * The result carries advice in two parallel forms: `recommendations` (English
 * sentences) and `recommendationCodes` (stable `{ code, params }` entries for
 * i18n). `preheatTemp.source` likewise has a stable `preheatTemp.sourceCode`.
 *
 * Both `coolingTime_t85` (model range 0.5-300 s) and `hazHardnessMax` (150-700 HV) are
 * clamped to their models' validity ranges; when that happens `coolingTimeClamped` /
 * `hazHardnessClamped` is set and the reported number is a boundary value, not a prediction
 * (at the 700 HV ceiling it is a lower bound — stainless and cast iron compositions hit it).
 *
 * @throws {RangeError} voltage, current, travelSpeed, or thickness is not positive
