ui(home): the redesigned home page: locker, live Trending board, phone-first layout - #78
Conversation
Two leftovers of the home redesign that are already on main: - Launch list: the token name shared one line with its quote badge, so a badged name got 2px at 360px wide, 32px at 390px and 66px on the tablet table (production shows it whole). Below 1024px the badge now drops under the name when the two do not fit. The phone grid's Buys / sells value stays on one line. - Star button: the tap gesture on its inner span made motion add tabindex="0", a second tab stop inside each of the 40 buttons. The attribute was absent under reduced motion, which logged a hydration mismatch, and a click left focus on the span. The press feedback is now the button's own :active state in CSS. Also corrects the comment on /rules: the walk-through opens the home page again.
The home page keeps the live river, the Just launched rail and the watchlist, and gets back the two things the redesign had moved away. Hero - "Launch a token. We take nothing." with the launch mechanism (token, pool, lock) drawn beside it again, two columns from 768px. - The second link is "See what's trending" (#trending): "How it works" is in the header, and the same drawing is on that page. - Short laptop screens draw the mechanism smaller, so the totals stay on the first screen at 1536x730, 1366x768 and 1280x720. Totals strip - Trades is the page's one big live figure: an exact count that rolls on every trade. Launches, volume, fees to recipients and the $0 platform fee sit beside it; phones get five compact rows. - The dollar readings are raw quote sums times the current price, so they drifted between polls with no trade. They now change only when something happened on-chain (a trade, a launch, a burn) or a quote lost its price. - No negative tracking on the mono figures (Space Mono Bold collides), and a figure shrinks instead of clipping when its value grows. - Sentences name "Robinhood Chain", never bare "Robinhood". Trending - A leaderboard: the leader's card and up to four runners, each with its wallets-trading bar on one scale, market cap, change, trades and volume. - "Leading" only in the hour window; the day window says "Top · 24h". - "How it's ranked" states the real rule from ranking.ts and is reachable by touch and keyboard. - Intentional layout for 0 to 5 tokens, a quote with no USD price, long names and large counts. A mouse or keyboard hold keeps the order only. The loading skeleton mirrors the page again (hero, strip, board, river), sharing its class strings with the hero so the two cannot drift.
The overhaul swapped the display font for Geist, which is about 23% narrower than the one the hero headline was tuned on, and widened the home column to 80rem. Re-stepped the headline so "We take nothing." fills its column at every width (two lines from 320 to 1920px) and updated the comments that still described the old mono face. The Trending board's avatars carry the same chain mark as every other list on the page. Chain marks are the official network logos already in the repo.
Trending says what its window is ("Trending today" / "Trending this hour") and
each card now shows its own last trades and reacts when one lands.
- Every card carries a tape of its last trades: a tick per trade, buys above a
hairline and sells below, taller for more dollars. Runners show how long ago
the token last traded. A run of same-side trades gets a x3 tag.
- A trade on a board token nudges its card (up for a buy, down for a sell, a
little more for more dollars, capped), lights its edge in the trade's colour,
lifts a "Buy $45" / "3 buys $210" figure off the card and springs a tick onto
its tape. Several cards in one poll take their turns 350 ms apart.
- Figures roll when they change. The text stays real text in the page.
- A card that changes place glides there and wears a ▲ / ▼ for a few seconds;
the new order waits a moment so the trade that caused it lands first.
- A new leader arrives as a hand-over: its rows come in one after another, a
line sweeps its top edge and it says whom it took the lead from.
- Only trades that are new, on the board and under two minutes old react. The
page's seeded trades are never announced again, nothing replays when a tab
wakes, and a trade under $1 only ticks the tape.
- Reduced motion: nothing moves. The edge and the figure fade in place; ticks and
numbers just change.
Data: one read-only query (each board token's recent trades, in the feed's own
order, remembered for 3 s) seeds the tapes on page load; the shared 5 s poll
delivers the rest. No schema change.
The hero keeps the locker and gets the polish production's has, then ends on one live line. - The totals move up into the hero's left column from 1024px, as a card: Trades is the big figure down its left side and the other four share a 2x2 beside it. The wide strip under the hero is gone on laptops (the left column was half empty), which brings the Trending board about 100px closer. Below 1024px the totals keep their own row. - The hero grid is three arrangements in one stylesheet (phones: copy, locker, totals; 768px: text beside the locker; 1024px: totals under the text), shared with the loading skeleton, which now matches the real page within 2px from 320 to 1440px. - Production's chain chip, icon buttons and proof chips are back. "See how it works" opens the rules guide (it replaces "See what's trending"). On phones the two buttons share a row; below 380px the second is just its tile. - A live line closes the hero: the newest launch or trade of a dollar or more, as a chain and a dollar amount only (no token name or picture in the hero's own space), linking to that token. The shared poll is its clock; no timer. - On the shortest laptop windows (about 657px under the toolbars) the headline and copy step down so the totals stay in view.
On a phone the token list used to start 3.6 screens down; it now starts 2.3 screens down (production's: 2.5). - Trending is a row to swipe below 1024px: 280px cards that snap at the left edge, the next one peeking out, so the section is 200px instead of 968px. The leader is the first card, drawn like the others; from 1024px the big leader card and the 2x2 of runners are unchanged. Each card keeps its tape, its reactions and its rank moves; the scroller leaves room above and below so a figure on a card's edge is not clipped. - The live panel is 510px instead of 687px: it reads "Live now" on a phone (its full name stays for assistive tech), the bubble field is 250px, the legend fits one row and one Latest card shows (the hero's live line carries the newest event). - The totals keep Trades as a row and put the other four in a 2x2. - The phone paragraph is 15px, as production's; sections are 24px apart. - The loading skeleton follows every one of these within 1-2px from 390px up.
When a real launch arrives on the shared poll, the hero locker's caption says
where ("New launch on Base") and its coin wears the token's picture for 15
seconds, then goes back to the mark. A launch lands every few minutes, so the
hero is alive between trades.
The coin is the one place a creator's picture reaches the hero, so:
- the picture must be one of our own stored images: an exact match on the image
host the server hands the client and on the key shape (t/<48 hex>.webp), with
nothing after it; any other URL, or no image store, means no picture;
- a launch whose name or symbol imitates a brand (this site, a chain, an
exchange, a stablecoin; digit and sign look-alikes folded) loses its picture,
and its caption still shows;
- no token name or symbol is ever drawn: the caption names a chain.
The launches the page was drawn with never react, an old one a waking tab sees
never reacts, and the newest of a poll wins. The shared poll is the clock (no
timer); the picture's own fade-out ends it invisible at exactly 15 seconds, and
reduced motion fades instead of popping. The locker keeps its caption and
drawing everywhere else (/rules) when given nothing.
The home page kept 77 animations running for ever: a beacon on every one of the 40 live rows in the token list, 15 floating bubbles, 9 pings in the side column, and the locker's. All of it costs a slow phone's main thread whether or not anyone can see it. The locker already paused itself; the rest now does too. A small hook marks a container while it is more than 160px off screen, and one stylesheet rule pauses every animation inside a marked container; they pick up where they were on the way back. The list, the side column and the live panel use it. The river view is left running: its marks drift on a real-time clock, and pausing it would make them lag. At the top of a phone's page 63 of the 76 are now held (only the locker's 13 run); each group wakes as it nears the screen and sleeps again after.
The header has no Launch button on a phone (it lives in the menu), so after the hero the page had nothing to act on. A filled pill now sits at the bottom of the screen from the moment the hero's own button has fully left it (the hero already reports that, for the header's copy), so the two are never on screen together. It steps aside for the footer so it never covers a footer link, sits under the header and its menu, and is not drawn from 640px, where the header has the button.
A five-lens review of the redesign (components, Trending logic, security, accessibility, performance), each finding challenged by a sceptic, left these: Trending - a failed tape read no longer fails the whole page: the cards just draw no trades until the next read (tapeOrNone, logged) - changing the window (1h <-> 24h) is a new list, not a race: no "New leader" and no rank moves across it - a card that remounts at a leader hand-over (the token's card moves between the leader's cell and a runner's) no longer replays the reaction its token already played: the chip, edge flash, nudge and fresh tape pips start from what arrives next - the first poll no longer announces trades the page's own feed already held (a busy runner's tape is shorter than the feed): TrendingStrip seeds `seen` from the feed's swap keys too - keyboard focus brings a partly visible card fully into the phone's swipe row Hero and layout - phones with larger text: the two hero buttons wrap instead of squeezing the filled one to an icon and pushing the page sideways (tablets and laptops are unchanged) - the Launch pill leaves <main>: as its last child it switched the spacing of the grid above it each time it came or went, moving the page height and the footer - HeroBackdrop.tsx deleted (nothing uses it since the hero lost its full-bleed band) The coin's picture (these are speed bumps, not a moderator) - a picture belongs to the first token that registered it: the feed marks a later token's copy (`image_reused`) and the coin shows its caption without it; if the ownership read fails every stored picture counts as a copy - the look-alike rule now undoes fullwidth/styled/accented letters, folds i, l, 1, | and ! together, joins "vv", and drops the picture for names that use letters from lookalike scripts (Cyrillic, Greek, Armenian, ...) or Latin letters outside a to z; Han, Kana, Hangul, Thai, Arabic and the like keep theirs - HERO_COIN_PICTURES=off (a Fly secret, no deploy) keeps the coin plain Tests: 1042 (1032 pass, 10 skipped); the source contracts that pinned the changed lines are updated, and the new rules have behaviour tests. Checked in a browser on the preview: phone widths 320-414 at 100-200% text, page height with the pill, keyboard focus in the swipe row, and six launches through the coin.

… render #78's check for a copied hero picture reads bb_launch_meta with an ILIKE over the feed's picture keys. That is a scan: about 32 ms at production's size (5,400 rows, 24 keys, measured on a stand-in table), and the home page asks on every render. CodeRabbit flagged it on #78. The read is now cached for 30 s per set of pictures (memo, bounded, a failure is not cached). Stale is safe: a copy is judged against the earliest registration, which is older than any copy and already in the answer, and a launch with a new picture changes the set, so it is read fresh. Behaviour is otherwise unchanged, including failing closed when the read fails.

Measured
This branch's production build against openlaunch.lol, Chromium, phone with the CPU slowed 4x. Share of the main thread busy while the page sits idle:
Cause: production's hero draws a full-height canvas and asks for about 240 animation frames a second even when idle; this branch has no canvas (about 1 a second). Layout shift over load plus 30 s of polling: 0.0009 on desktop, 0 on mobile. Caveats: production was measured over the network with its real scripts, this branch from a local build, and the numbers move a few points between runs. On a laptop the list starts lower than on production (1,723px vs 1,360px): the locker and the totals card are deliberate.
Review
Before this PR, five independent reviewers (components, Trending logic, security, accessibility, performance) read the branch read-only, and a sceptic then tried to refute each serious finding. Nine of the eleven findings that survived are fixed in the last commit:
Left as they are: the locker's three SVG dash animations are the largest idle cost still in the hero (optional; the hero is about 3x lighter than production's). Shift+Tab can leave focus under the sticky header, exactly as on production; a global
scroll-padding-topwould touch every anchor jump, so it belongs in its own PR. Smaller: Tab order at 1024px+ visits the locker before the totals card; rank-move chips and the phone "New leader" chip have no screen-reader text; at 1024x657 the totals notes sit below the fold; chip counts are capped by the poll's 24-event feed. Safari and Firefox are untested.The coin's picture: read this
Rules: our own stored images only (exact host and key); a picture belongs to the first token that registered it, so a later token's copy shows the caption without it; a look-alike name or symbol (fullwidth, accented, i/l/1,
vv, letters from Cyrillic, Greek and similar scripts) shows the caption without it; never a name or symbol; 15 seconds. If the ownership read fails, every stored picture counts as a copy.These are speed bumps, not a moderator. A creator can still upload a picture of their own that resembles something, and it will appear on the coin for up to 15 s (picture-and-name rows on the list already work this way, the coin is just larger). Off switch: set
HERO_COIN_PICTURES=off(a Fly secret: it restarts the app, no deploy) and the coin stays plain while the caption still reacts.Deploy notes
bb_launch_metatable is about 350 rows in my local copy of the live data; the read is a scan, so indeximage_urlif the table grows large). Its failure is logged and fails closed.Tested
