- theme: store accent separately for light/dark (theme-core/controls)
- en contacts: WhatsApp card instead of VK (wa.me link)
- Activity: add GitHub card (logo webp) in both locales
- mp-card__image border uses --line to match card (less contrast)
- Added secondary FAB button 'Печать' with printer icon (window.print)
- Created printer.svg icon for the print button
- Added .fab-secondary__ico--print CSS class
- Fixed html2pdf color-mix() issue: buildCleanClone() creates a deep clone
with all computed styles inlined, all stylesheets removed, and
pseudo-elements converted to real DOM elements before passing to html2pdf
- Two separate handlers: pdfBtn for download, printBtn for print dialog
