/* Shared diff rendering — Work tab File diffs pane, Work Session Git section.

/* diff2html positions .d2h-code-linenumber absolutely with no top/left, and
   defines no positioned ancestor of its own. Without this rule the line numbers
   resolve against the initial containing block — fine when the page itself
   scrolls (Work tab), but broken inside an element that scrolls (the Work
   Session Git section's #wsg-detail), where the code scrolls and the numbers
   stay pinned. overflow:auto alone does not establish a containing block; a
   position does. Placement is unaffected, since top/left are auto and the
   static position is used either way. */
