The quantity went into the .sub line, which is nowrap + ellipsis: a
28- or 38-character SKU truncated it, so the number fell off the right
edge and pushed the in-cart count out with it. The sub line is back to
what it was — sku, brand, unit, N in cart — and the quantity now sits
under the price, right-aligned, where nothing truncates it.
The POS tests asserted the file's prose rather than its expressions, so
five mutations of the implementation all passed them: a min_qty cue, a
lost zero boundary, a clamp, a round and the segment deleted. They now
pin the expressions, the interpolation, the class wiring and the dark
rule's colour value. All seven mutations tried are killed.
A non-numeric current_qty rendered "NaN in stock" and was not badged —
NaN <= 0 is false. It now falls back to 0 and badges.
Bumped the service-worker cache: pos-app.js and pos.html are both
served cache-first out of the shell, so without a new CACHE name the
tills keep the old ones.
