+// UEB tests for GitHub issue #529, from the second (BANA) source document:
+// "Guidance on Transcribing Mathematics and Science in UEB", Section 5
+// "Preference on grade 1 indicators with technical expressions" (RUEB Section 5.9; GTM Section 1.7, 2025 update).
+//
+// Notes on scope:
+// - Examples 5-1 (x + y = 6), 5-7 (x^2 + y^2 = C), and 5-10 (a/b + c/d) are exact duplicates
+//   of bana_5_1, bana_5_2, and bana_5_3 already in iceb.rs (same source examples, from the
+//   2019 BANA doc), so they aren't repeated here.
+// - Example 5-14 (a^n * a^m = a^(n+m)) uses the *same* MathML as the existing bana_5_4 test in
+//   iceb.rs, but this document gives it *different* expected braille: two separate grade 1 word
+//   indicators instead of one grade 1 passage. This is kept deliberately (as
+//   bana2025_5_14_power_multiplication) as a direct old-vs-new contrast for issue #529 --
+//   bana_5_4 documents the old (pre-2025) behavior, this documents the new one.
+// - Example 5-9 ("24. The slope of l1 is 5/3 and l1 || l2.") is skipped: it's not tagged to the
+//   2025 update, and the math is too interleaved with sentence prose to cleanly isolate per the
+//   "math parts only" scoping used elsewhere.
+// - Examples 5-5 and 5-6 are matrices. The visual layout came through as garbled OCR text, so
+//   the MathML here is a best-effort reconstruction from the (reliable, copy-pasted) braille
+//   alone. If these fail in a way that doesn't look like an indicator-choice issue, check the
+//   PDF directly before trusting the MathML.
