/* Arsalan Asad — the presentation all four public pages share. Extracted from the inline
   <style> blocks on 18 Sep 2026 (audit P2-4) after checking that each rule below is identical on
   every page and that moving it changes no cascade relationship. Page-specific rules stay inline.

   One relationship did move: each page's inline `.btn` writes `border: 1px solid transparent`, and a
   shorthand restates every longhand it covers, so at equal specificity it over-wrote the outline
   buttons' `border-color` below. Those three rules are therefore written on `.btn.btn--outline`, which
   outranks a lone `.btn` whatever order the two files are read in. `social/verify_17c_css.py` holds the
   check that no rule here loses a declaration to a shorthand written later. */
