/* shell.css — the shared shell, defined ONCE.
 *
 * Every rule in this file was byte-identical (whitespace-normalised) in all four page
 * <style> blocks: index, projects, writing, radar. It is the reset, the paper/grid body,
 * the sidebar, the search overlay, the contact gate, the footer — the chrome that must
 * look the same everywhere (see SHARED_SHELL.md).
 *
 * Loaded BEFORE each page's inline <style>, so a page can still override anything here
 * without touching this file. Page-specific rules stay in the page.
 *
 * DO NOT copy a rule from here back into a page to tweak it — change it here, or override
 * it in that page's <style>. Editing four copies is what let 16 selectors silently drift
 * apart before this file existed.
