   .button-8 — primary outlined CTA, large variant of the chip family
   ─────────────────────────────────────────────────────────────
   Halim 2026-05-15: harden the design system so old buttons (Send
   an Email, Vote Now, Reach Out, Contact Halim) read as the same
   family as the new corner chips (CONNECT, HUMAN/MACHINE). The
   Connect aesthetic wins: outlined, monospace, uppercase, 4px
   radius. Just bigger here because these are primary page CTAs,
   not corner micro-buttons.

   Family hierarchy:
   - .chip-name (chrome.css):           outlined micro-chip (corners)
   - .mode-toggle__option (chrome.css): outlined micro-chip with radio
   - .button-8 (here):                  outlined LARGE CTA — same family,
                                        bigger padding + type
   - .signup-bar__submit (chrome.css):  filled-ink variant of .chip-name
   - .section-pill (below):             color-coded decorative pill,
                                        kept distinct (content anchors)
