fortplot_pdf_axes Module

PDF axes, grid, tick drawing, and plot frame operations

Thin coordinator module that delegates to specialized sub-modules: - fortplot_pdf_axes_tick_data: tick position/label computation - fortplot_pdf_axes_drawing: frame, tick marks, minor ticks - fortplot_pdf_axes_text: title/label text rendering with mathtext
