       EASY CUSTOMIZATION
       Change these colors or spacing values to tweak the whole page.
       To add a tool: copy one <div class="tool-entry"> ... </div>.
       Optional: add a <details> block for mirrors or source code (small chain-link icon).
       To add a category: copy a full <section class="category ...">.
