/**
* Reverse-battery, transient-protection, and EMI-input section from sheet 2 of
* TI TIDA-050008 (native Altium archive TIDRXT8).
*
* Coordinate transform: Altium positions are converted from mil to mm using
* x_mm = x_mil * 0.0254 and y_mm = y_mil * 0.0254. This child then applies the
* pure translation (x_tsx, y_tsx) = (x_mm - 21.716, y_mm - 19.812). There is
* no scaling or reflection. Small, documented native-symbol alignment deltas
* keep the Altium wires orthogonal despite different tscircuit pin anchors:
* P1/P2 rotate 180 degrees and use y=21.822/19.058 mm, TP2/TP7/C24 use
* x=6.604 mm, R14 uses x=3.9497 mm, R1/R2 use y=19.431 mm, and D4/R3 use
* x=18.742 mm. C24 rotates 90 degrees and TP7 rotates 270 degrees so the
* capacitor column and its two test points connect end-on. To compensate for
* the larger native tscircuit symbols while keeping the two source sections
* intact, the reverse/protection section is translated +4 mm in X and the
* complete System EMI Input Filter section is translated +1 mm in X. This
* moves the full drawing right and reduces the otherwise oversized D6-to-CF1
* empty span by exactly 3 mm; all Y coordinates and within-section offsets
* remain those of the Altium source.
*
* The released schematic displays Q1 as SQJ465EP, while TI's released BOM
* specifies the fitted manufacturer part number SQJ461EP. The component keeps
* the authoritative BOM MPN and the released five-terminal Altium pin map.
