Since the grid transport change, opening a Pokémon fetched
/api/pokedexes/[id]/entries/[entryId]. That request re-scanned the whole
dex to authorise one entry, on top of an auth call and an ownership
query, and production runs its functions in a different region from the
database — so each card took seconds to fill in. The page's 60-second
reconcile also wiped the detail cache, making cards refetch about once a
minute.
Details are catalog text plus personal notes, so the dex is now read once
per account/dex in the background at the interactive/idle boundary and
fills that cache; a card opens straight from memory. That read reuses the
existing combined-data endpoint, which gains an opt-out for its count
query since a caller taking every row already knows the total.
The per-entry endpoint stays as the fallback for a card opened before the
background read lands, and now checks membership for the single entry
instead of materialising the dex. Catch status still comes from the live
grid row and any queued write, so a cached detail cannot show stale
progress.
The packed grid transport and virtualised rendering are unchanged.
The server load fetched a full combined-data page at a 9999 item page size,
carrying detail text and ownership fields the grid never renders, and the client
re-fetched the same payload after hydration.
Load a trimmed grid row instead and pack it as positional tuples so field names
are not repeated for every one of a thousand-plus entries. Entry detail is
fetched on demand from the new per-entry endpoint when a cell is opened, and the
grid marks itself interactive so other page-start work can queue behind it.
- Ship one hashed Tailwind stylesheet instead of two (one render-blocking)
- Compress responses in-app (brotli/gzip, streaming-safe) and precompress
the node build so local and CI measurements match production
- Validate the Supabase session once per request
- Render the homepage immediately and stream public stats
- Stream a Pokedex's entries with the page instead of fetching after
hydration, running the rows and count queries in parallel
- Shrink the avatar and offline placeholder images, fix layout shift,
contrast, link names and missing meta descriptions
- Add Lighthouse CI (mobile + desktop) with score and metric budgets,
bundle-size budgets in the build tests, and signed-in speed scenarios
