/* ags 92 – B2B: akčná MOC z XML feedu (moc1.js.txt, verzia 2026-11-01a)
 * Problém: prenos Money → BUXUS plní pole „Akciová MOC“ len pre SK a aj tam ho hodinový import maže; CZ/HU nikdy.
 * Partner potom vidí plnú MOC a maržu 100–130 % namiesto ~20 %. (zadanie-ui42-jetsoft-akcna-moc-prenos-money-buxus)
 * Riešenie (len zobrazenie): pre každý produkt v zozname (katalóg, značka, hľadanie) a na detaile sa akčná MOC vezme
 * z nočného Indexu B2B (= XML feed, pole AKCNAMOC / AKCNIMOC / SPECIAL_RETAIL_PRICE) a ak ju BUXUS v karte nemá,
 * doplní sa riadok „Akciová MOC“, bežná MOC sa prečiarkne a marža % + hodnota marže sa prepočítajú rovnako ako BUXUS
 * (hodnota = akčná MOC bez DPH − VO; DPH SK 23 / CZ 21 / HU 27 %). Kde BUXUS akčnú MOC má, skript nič nemení.
 * Cenový blok cena* číta ten istý DOM → dostane správne čísla automaticky. Košík, VO a faktúry sa nedotýka.
 * Zapínanie: window.agsMoc = { mode:'off'|'preview'|'live', test:[odtlačky firiem], api:'…/exec', ttlHours:6 }.
 * Vypnutie: mode:'off' alebo zmazať riadok include v Containeri 22. Meranie: ags_moc_fix {miesto, n}, ags_moc_index, ags_moc_stop.
