fix: references at the end, never in the body

A slide carrying [1] markers is unreadable from the back of a room, and an
article that cites inline reads as a paper rather than as teaching material. The
model is now told explicitly not to cite in the body — no bracketed numbers, no
parenthetical "(Nelson, p. 2604)" inside sentences — and to put everything it
drew on in a References section at the end, which in a presentation is the final
slide.

Checked rather than assumed: a six-slide deck generated through the grounded
path contains zero in-text citation markers, and ends with a References slide.
The prose keeps the specificity that grounding is for — bilirubin produced at
two to three times the adult rate, conjugation immature until about two weeks,
thresholds in mg/dL — without a single marker interrupting it.
