style.py — Shared Plotting Style for EE1204 Simulation Assignment
=================================================================

This module sets consistent matplotlib aesthetics (fonts, sizes, colours,
colour-maps) so that every figure across all three questions has a uniform
professional appearance.

Usage
-----
    import style          # simply importing executes rcParams update

    # Then use the colour constants anywhere:
    ax.plot(x, y, color=style.PLATE_POS)
