…e wide layout The hero was set at a fixed 200px, which put a four-figure spend past the edge of the frame: "$2,390.99" is 959px wide against the square card's 936px of content, and against the wide card's 504px hero column it ran off both edges and printed over the model rows. It is now fitted to the value against the width it actually has, capped at 168px on square (132 for a long model list) and 120 on wide, so a short value gets the cap and a long one steps down. The card is rasterized in the same tick it is rendered, so there is nothing to measure; emWidth estimates per character class, within ~2% of the real thing for the strings the card sets. Dollar figures on the card drop their cents from $100 up. At hero size the cents are a third of the width of "$2,391" for a precision nobody checks. The page's own tiles and tables keep them. The wide card also overflowed vertically, running the hero over the title and the model rows through the stats rule: 630px of frame cannot hold the square card's arrangement of hero, then rows, then a full-width stats band. Wide is two columns now, the claim (hero plus its supporting stats) beside the evidence (the model rows), which gives the rows the whole middle height and the hero a column narrow enough to size type against. Its rows get their own narrower name and value columns, so the bar no longer collapses to nothing and push the token counts off the edge of the card. Row height now falls out of subtracting the real band heights from the frame rather than two hand-tuned budget constants, and the e2e overflow check now covers scrollWidth: only that would have caught the wide hero.

WalkthroughThe share card now uses ratio-aware layouts and bounded hero sizing. Spend headlines round values of $100 or more to whole dollars. Component tests, E2E checks, and dashboard documentation cover the updated behavior. ChangesShare card presentation
Estimated code review effort: 3 (Moderate) | ~25 minutes Mergeability Score: 🔵 Low · up to The share-card layout now fits large values and wide cards, but long model names are explicitly truncated only in the wide layout; square cards may still allow names to overlap the bar. This is a bounded visual risk that is mergeable with owner awareness or a follow-up. Possibly related PRs

133-136: 📐 Maintainability & Code Quality | 🔵 Trivial | 💤 Low valueAssert the hero node exists, so a structural change fails clearly.
If the selector stops matching,
Number.parseFloat("")yields NaN, and every assertion below reports a comparison against NaN rather than a missing hero. A one-line check keeps the failure message pointing at the real cause.🔍 Proposed tightening
const heroPx = (container: HTMLElement) => { const node = container.querySelector<HTMLElement>('[style*="font-weight: 700"]'); - return Number.parseFloat(node?.style.fontSize ?? ""); + expect(node, "hero node not found").not.toBeNull(); + return Number.parseFloat(node!.style.fontSize); };One coverage note while you are here: no case pairs 9 rows with a two-line title, which is the combination I flagged on
ShareCard.tsxlines 219-235. A case there would settle that arithmetic quickly.🤖 Prompt for AI Agents

63-88: 📐 Maintainability & Code Quality | 🔵 Trivial | 💤 Low valueConsider a hard clamp behind
MIN_HERO, since the floor can win over the fit.
Math.max(MIN_HERO, ...)can raise the size above the size that actually fits. At 56px, about 7.0 em is all that fits the 400px landscape hero column.ShareCard.test.tsxline 190 pins exactly such a case:"$123,456,789,012,345"is roughly 10.7 em, which needs about 599px at 56px. The hero string carries no break opportunity, so it cannot wrap and it prints over the model rows.The values that reach this slot are formatted spend and counts, so this needs a very large gateway to trigger. Still, one line on the hero container makes the floor safe by construction rather than by argument:
🛡️ Optional guard on the hero container (lines 257-267)
flex: isLandscape && hero !== undefined ? `0 0 ${heroColumn}px` : "0 0 auto", width: isLandscape && hero !== undefined ? heroColumn : undefined, + overflow: "hidden", }}The comment on lines 63-68 could then say the floor is safe because the frame clips, which is a stronger claim than the current one.

- Around line 239-241: Update the square-card name truncation in ShareCard using
the existing emWidth estimator and nameWidth so the character limit is derived
from the 360px column rather than the fixed 28-character bound; preserve the
current landscape limit, and add a clipping backstop to the name span so
unestimated names cannot overflow into the value column.
- Around line 219-235: Update the row sizing logic around rowHeight and rowsArea
so the maximum 9-row layout fits within the middle block for both landscape and
square cards, including square cards with a stats band. Preserve readable row
content by applying suitable clipping or reducing row spacing/count only in
tight layouts, and ensure the resulting rows do not overflow adjacent title,
caption, footer, or stats content.

…e estimator's error Sizing the title slot from emWidth traded a clipped pixel for a clipped word. The estimator's per-class averages are tuned on the formatted numbers the hero sets and run about 10% low on prose against the Arial-metric stacks the card falls back to, since no font is bundled and the rasterized SVG cannot fetch one. A wide-card title the estimate scored as one line therefore wrapped to two and lost the second line to the slot's overflow: measured over 500 generated 34-to-60-character titles, 105 of 1000 renders clipped under Arial metrics, against none before the slot became a fixed height. The wrap is now decided at 0.85 of the real width, which covers the observed error in both shapes and under three font stacks. The slot also takes an exact pixel line height rather than a unitless 1.2, so it is a whole number of line boxes, plus 4px for fonts whose descenders run past their own line box (Liberation Sans does, by 3px at this size). Three comments claimed more than the code does, and are corrected rather than left to be trusted: MIN_HERO can overflow when it clamps up (at roughly $100T of spend, which no formatter here emits), emWidth's accuracy holds against the fonts it was measured on rather than every stack, and the e2e width check cannot reproduce the hero bug it named, because that seed prices nothing and the hero is a two-digit request count.

Pull request overview
This PR updates the dashboard “Share as image” usage card so large dollar values and the wide (landscape) layout no longer overflow the fixed card frame, and adjusts spend formatting for better headline legibility on the card.
Changes:
- Replace fixed hero sizing with estimated text-width fitting (
emWidth+fitHeroSize) and rebuild the wide card into a two-column “claim/evidence” layout. - Introduce
formatUsdHeadlineso share-card spend drops cents at $100+ while leaving table/tile formatting unchanged. - Expand unit/e2e coverage to catch horizontal overflow and verify sizing heuristics.

Description
The share card's hero was set at a fixed 200px, so a four-figure spend ran off the frame.
$2,390.99is 959px wide against the square card's 936px of content, and against the wide card's 504px hero column it ran off both edges and printed over the model rows. The hero is now fitted to its value against the width it actually has, capped at 168px on square (132 for a long model list) and 120 on wide: a short value gets the cap, a long one steps down. The card is rasterized in the same tick it is rendered, so there is nothing to measure;emWidthestimates per character class and lands within ~1% of Chromium for the numeric strings the hero sets (pinned in a test).Dollar figures on the card now drop their cents from $100 up (
$2,391). At hero size the cents cost a third of the width for a precision nobody checks. The page's own tiles and tables keep them.The wide card was broken in both axes, not only horizontally: the hero also ran over the title and the model rows crossed the stats rule, because 630px of frame cannot hold the square card's arrangement of hero, then rows, then a full-width stats band. Wide is two columns now, the claim (hero plus its supporting stats) beside the evidence (the model rows). That gives the rows the whole middle height and the hero a column narrow enough to size type against. Wide rows also get narrower name and value columns, so the bar no longer collapses to zero and push the token counts off the edge.
Row height now falls out of subtracting the real band heights from the frame rather than two hand-tuned budget constants.
The second commit fixes a regression the first one introduced: sizing the title slot from the estimator traded a clipped pixel for a clipped word.
emWidthruns about 10% low on prose against the Arial-metric stacks the card falls back to, so a wide-card title scored as one line wrapped to two and lost the second line to the slot's overflow (105 of 1000 generated titles under Arial metrics, none before the slot became a fixed height). The wrap is now decided at 0.85 of the real width, and the slot takes an exact pixel line height plus 4px for fonts whose descenders run past their own line box.Verification. Rendered in headless Chromium across both shapes x 1/3/5/9 rows x both themes, plus the empty state, long titles,
$4.20and$1,234,567: no frame overflows in either axis and no element spilling its box, repeated under three font stacks. Before this, wide laid out 1364px of content in a 1200px frame.One judgment call: wide truncates model names to 22 characters (
claude-sonn...5-20260514) to keep the bar visible. Widening that column pushes the bar back toward the state this fixes.PR Type
