### Description
    The Fisheries & Marine Ecosystem Model Intercomparison Project (FishMIP) provides projected changes in fish biomass under SSP1-2.6 (low-emissions) and SSP5-8.5 (high-emissions) scenarios. Projections are presented as decadal means for 2041–2050 (medium-term) and 2091–2100 (long-term), expressed relative to the 2005–2014 reference period.

### Processing steps

    1.	Download all files from https://rstudio.global-ecosystem-model.cloud.edu.au/shiny/FAO_report_shiny/ for the Antarctica LME and file in cwd/input

    2. Run 02_grid_data.py
        * Read all CSV files from input/
        * Convert point values representing 1° grid-cell centres into centred 1° × 1° raster grids
        * Create one 5-band GeoTIFF for each input CSV, covering each time period and emissions scenario
        * Write band descriptions as:
            - Band 1 = min_change
            - Band 2 = max_change
            - Band 3 = mean_change
            - Band 4 = median_change
            - Band 5 = sd_change
        * Set NoData to -9999
        * Save outputs as DEFLATE-compressed EPSG:4326 GeoTIFFs in output/
