- introduces semantic CSS tokens (--surface-1/2/3, --border-subtle/strong,
--hairline, --shadow-sm/md/lg/xl) with distinct dark and light values;
fixes broken light theme caused by hardcoded rgba(255,255,255,X)
- drops glassmorphism on cards — solid var(--surface-1) with 1px border
and layered shadows; glass kept only for aurora page background
- introduces .card/.card-raised/.card-hero utility classes
- Home page restructured into a bento grid:
* greeting row with inline day/date
* hero weather (64px number, large icon, ощущается/влажность/ветер)
next to the tram widget (1fr 1.1fr)
* forecast as a single hairline-separated band (no per-day cards)
* events+notes in a 2-column grid; events card combines today and
tomorrow with a divider; notes card styled via surface tokens
- TransportWidget repainted to use tokens, larger numbers (32px for the
next arrival), imminent highlight uses color-mix against surface-2
