+ * @param		abbreviation - abbreviated unit name, e.g. 'B'
+ * @param       ... - the conversion factor definition for the unit type. Taken as variadic

+/// @brief      Formats a `wpi::units::unit` for `std::format`, `std::print`, `std::println`, and `std::format_to`,
+///             with a units-aware mini-language.
+/// @details    The value-spec (everything before an optional `%`) is delegated to the underlying arithmetic
+///             type's `std::formatter`, so the full standard numeric grammar is supported (precision, width,
+///             fill/align, sign, `#`, `0`, `L`, type, …). The unit-opts (after `%`) control the label form,
+///             whether the value/unit are shown, and the separator. This support needs only `<format>`, not
+///             iostream, so it is available even under `UNIT_LIB_DISABLE_IOSTREAM`.
+///
+///             Grammar: `{:` value-spec [ `%` unit-opts ] `}`, where unit-opts are, in any order:
+///               - `a` own abbreviated label (default), `n` own full-name label — neither converts the value
+///               - `b` convert the value and label to SI base units (`6 ft` → `1.8288 m`)
+///               - `v` value only, `u` unit only
+///               - `'`…`'` a separator literal between value and label (`''` none, `'_'`, `'\t'`, …)
+/// @tparam     U    any unit type — the `unit<...>` template itself OR a named unit derived from it
+///                  (e.g. `meters<double>`), matched through the `wpi::units::UnitType` concept so a named unit
+///                  formats the same as its `unit<...>` base.

   When going from C++ to Python (eg, return values), the units that a user
   gets as a float are in whatever the unit was for C++.

   When going from Python to C++, the units a user uses are once again
   whatever the C++ function specifies:
 
-    void setFeet(wpi::units::foot_t ft);   // must pass a float, it's in feet
-    void setMeters(wpi::units::meter_t m); // must pass a float, it's in meters

   issues with implicit conversions when default values are used that don't

+// Regression guards for the #378 ODR audit and the dimension-keyed physical-quantity concepts.
+//
+// Issue #378 is a cross-translation-unit type-identity divergence: arithmetic that yields a compound result
+// (e.g. `meters/seconds`) rewraps to a "canonical named type" (`meters_per_second`) via an ADL registration that is
+// only visible in a TU that included the result's dimension header; a TU without it sees the plain `unit<...>` base.
+// The fix emits a PascalCase, dimension-keyed concept per dimension (`wpi::units::Velocity`, `wpi::units::Force`, ...) so a
+// computed result classifies the same way regardless of which dimension headers a TU included — dispatch on the
+// concept cannot flip by link order. These tests codify (1) that the concepts classify by dimension and reject the
+// wrong one, (2) that concept-based overload dispatch selects correctly at runtime, (3) the VALUE / DIMENSION /
+// LAYOUT / SERIALIZATION safety invariants that make the residual type-identity split value-safe (so a future rewrap
+// change trips a test instead of silently corrupting), and (4) the proven-STABLE `sqrt` reduction. The library is
+// dimension-only by design (torque and energy share a dimension), so these tests assert dimensions and values only —
+// never a physical-"kind" identity.
