v0.7.1

Changed

• PWA install + update reliability — bundle the i18n overlays and shrink the service-worker precache from 4,456 to 355 entries; stop precaching ~1.7 GB of imagery (was blocking SW install on iOS); register the SW under the BASE path with silent update rollover; add guardrails so silent update-stall regressions can't recur.

Added

• MobileControlsDrawer — a unified, non-blocking partial drawer. /explore and the surface routes (/earth, /mars, /moon) gain a 3-tab drawer accordion, a top control cluster across all five canvas routes, and a station accordion on /iss + /tiangong.
• Card back-chain extended to /explore bodies and surface sites; planet missions link to their real mission records with a detail-card back button.

Fixed

• Mobile: flat-patch layout, stations-list close, /fly speed popover, lens stacking, surface chips, /fly accordion, /plan lens offset, and surface immersive-mode collisions; keep the mobile footer to one line (build date → tooltip); bottom-sheet scrim + z-order so detail panels always close.
• Preflight: clear dead-holder locks instantly + fail-fast on lock contention.

Testing

• Migrate the mobile e2e specs to MobileDrawerGroup; fix a11y / hang regressions; regenerate visual snapshot baselines.
