Architecture and gotchas for packages/stage — the Threlte/Three.js map renderer (layers, two-pass rendering, shaders, coordinate flips, performance tiers, disposal). Load whenever working in packages/stage, on shaders, or on the stage's consumers (apps/docs stage route, the web editor's Stage integration).

Data-layer patterns for apps/web — apiFactory error semantics, mutationFactory/handleMutation, drizzle schema conventions, the Y.js/PartyKit realtime model (no save pipeline!), auth, R2 uploads, Stripe, email, env vars. Load when adding/changing API endpoints, queries/mutations, schema, realtime behavior, or server logic in apps/web.

Conventions for building/editing components in packages/ui (@tableslayer/ui) — file anatomy, Svelte 5 props/snippets patterns, BEM + CSS token styling, theming, toast/popover gotchas, and how to visually verify changes in apps/docs. Load whenever creating or modifying anything under packages/ui.
