human-flow P0-P1 fixes for radio.azcomputerguru.com:
- K1: skip-to-content link (first tab stop) + id/tabindex on <main>.
- K2: global :focus-visible ring (accent outline) across links, buttons,
inputs and player controls; reveal the seek-bar handle on focus.
- K3: mobile menu a11y — aria-expanded/aria-controls, Escape closes and
restores focus to the toggle, focus moves to first link on open.
All token-based, no emojis. Not built (node_modules absent on this host).
