• Essential / session guardians: authentication cookies & JWT complements preserving TanStack Router guards without perpetual re-login friction — disabling nukes dashboard coherence.
• Preference tensors: theme selectors (light/dark/os-derived), accessibility toggles, motion reduction echoes mirrored into localStorage for hydration symmetry.
• PWA & funnel reminisce: install-banner dismissal timestamps, lightweight cart continuity shards — minimizing accidental abandonment without creepy cross-site stalking.

Hosting/CDN partners may ingest anonymized performance waterfalls — latency histograms, error strata — aiding incident retrospectives. Cross-reference personal-data intersections inside our Privacy Policy; no surreptitious cross-domain ad auctions execute here today — future monetization experiments mandate refreshed disclosures prior activation.

Browser privacy dashboards let you evict categories wholesale — anticipate fractured sessions afterward. Ephemeral browsing compartments discard many primitives post-close — ideal for shared-terminal merchants taking microloan devices into field logistics.

Structured serialization caches accelerate storefront revisit latency — clearing site data resets experiential motifs but may logout concurrently — acceptable tradeoff for forensic cleanliness post-account-sharing mistakes.

Experimental heatmaps or friction analytics won't silently deploy — proactive notices precede collection regime shifts. Skepticism welcomed — ping operators if telemetry claims drift from observed behaviour.
