M1 — PWA mechanics: - Generate real app icons (apple-touch-icon + manifest 192/512/maskable) via pure-stdlib gen_icons.py; iOS uses apple-touch-icon, not manifest icons. - viewport-fit=cover + env(safe-area-inset-*) on header/input/menu so content clears the notch and home indicator. - Dynamic height pinned to the VisualViewport (height + offsetTop, re-measured across the keyboard animation) so the input stays above the iOS keyboard; 100dvh fallback. Kills the squish/gap bugs in standalone mode. - overscroll containment; flesh out manifest (scope, portrait, maskable). M2 — visual redesign: - Realign style.css to the warm low-glow RTO palette already used by the standalone pages (#0e0e0e panels, #2a1d12 borders); remove the neon saturated-orange borders and ~15 glow shadows. - Reserve filled accent for one element (Send); glow only on status pulse + input focus. Flat warm message bubbles with tail corners. - Reclaim the mobile header into [≡] Lyra · [status dot]; drop the redundant status bar (relay status now the header dot, updated in checkHealth). - prefers-reduced-motion support; fix undefined var(--text); real light-mode tokens.

"""Generate Lyra PWA icons with no third-party deps (pure stdlib PNG writer).

Design: RTO warm/low-glow — near-black field, a soft orange ambient glow, and a
|
|
luminous gold-orange ring (the "orb/portal"). iOS masks corners itself, so icons
|
|
are full-bleed squares. Run from anywhere; writes PNGs into ./static.
