9	* Pins SBR_Review_Alert_Frontend::star_fill_states() — the one formula that
10	* turns an average rating into per-star full/half/empty glyphs (SMASH-1616).
11	*
12	* This is the AUTHORITATIVE side of a cross-language contract: the popup
13	* template (templates/review-alerts/popup.php) consumes this, and the
14	* customizer's React starFillStates() in ReviewAlertPreview.js mirrors this
15	* exact formula. The original bug was the preview pre-rounding the average
16	* (Math.round(4.7) -> 5 solid stars) while the frontend drew 4 + a half — so
17	* "4.7 -> 4 full + 1 half" is the case that must hold on both sides.
