This PR adds generic, low-maintenance unit tests to the package. These tests are designed to be parametrized and introspection-driven to minimize boilerplate and stay resilient to future new palettes/scales.
tests/test_utils.py: hex/rgb round-trip, alpha application (#RRGGBBAA), color interpolation endpoints and sampling.tests/test_palettes.py: introspection across allpal_*functions; discrete and continuous behavior, reverse ordering, alpha handling, and error cases (unknown palette, invalid alpha).tests/test_scales.py: discrete scale dataclasses (_aesthetics, palette callable,alphaviaInitVar), continuous factories return types (gradientn), British alias identity, and package root export alignment.Code coverage is 100%.
