PticaDrawer: proper modal focus management —
- focus-trap: Tab/Shift+Tab wrap inside the dialog (focusables re-queried per
Tab so it survives lazy panels/sub-tabs), focus-already-outside pulled back in;
- focus-restore: the trigger element is captured on open and re-focused on close
(guards null + detached node);
- onClose held in a ref so the effect depends on [open] only — fixes focus
thrashing when the host's URL/searchParams change mid-open.
Esc/scrim close, body-scroll-lock, role=dialog/aria-modal preserved.
Cleanups (code-review follow-ups):
- MassingScene: drop duplicate initial mass build (floors/sections effect owns
it); corrected the effect-ordering comment.
- Static inline styles → CSS-module classes (scan/gauge/score/spaced rows).
- DrawerPrimitives: remove !important on .dtabActive via specificity
(.dtabs button.dtabActive).
- Remove unused SoonCard component + its CSS.
tsc/lint/prettier clean; next build green (route bundled). ptica-only, no any.
