/* ══════════════════════════════════════════════════════════
   Teacher Toolshed — shared TOOL stylesheet, v2 (editorial)
   Replaces css/toolshed.css.

   Load order in every tool page:
     1. Google Fonts (Playfair Display + Newsreader + Archivo)
     2. css/theme.css      ← tokens, reset, links, focus, footer
     3. css/tools.css      ← this file (app chrome + controls)
     4. the page's own <style> block (layout only)

   theme.css owns: reset, --ink/--paper/--rule/--accent, the three
   fonts, .column, .t-display/.t-body/.t-meta, focus rings.
   Never redefine those here or in a tool page.
