Description: Provides a reproducible and modular workflow for absolute
        microbial quantification using spike-in controls. Supports both
        single spike-in taxa and synthetic microbial communities with
        user-defined spike-in volumes and genome copy numbers.
        Compatible with 'phyloseq' and 'TreeSummarizedExperiment' (TSE)
        data structures. The package implements methods for spike-in
        validation, preprocessing, scaling factor estimation, absolute
        abundance conversion, bias correction, and normalization.
        Facilitates downstream statistical analyses with 'DESeq2',
        'edgeR', and other Bioconductor-compatible methods.
        Visualization tools are provided via 'ggplot2', 'ggtree', and
        related packages. Includes detailed vignettes, case studies,
        and function-level documentation to guide users through
        experimental design, quantification, and interpretation.
