/* Styles for the <nessemble-assembler> Web Component. Scoped to `.na-*` classes
   to avoid clashing with host page CSS (mdBook docs, the marketing site).

   Sizing is `em`-based (never `rem`) so the component scales with the host
   page's body text. mdBook sets the root font-size to 62.5% (1rem = 10px), so
   `rem` units would render the editor/output far smaller than the surrounding
   prose; `em` inherits the 16px body size instead. The monospace editor and
   byte output are sized at 0.875em to match a documentation code block (mdBook's
   `code` is 0.875em), so the assembled bytes line up with an adjacent snippet. */
