How this was measured

Coverage is detection coverage, not a verdict — it counts the conversion tactics we could prove are present, out of the 11 that apply to a saas funnel.

Measured by Roentgen 1.20.1, one of our versioned rulesets. A capture is read once and its measurements freeze there, so the stamp says which ruleset read this one.

Absence is a measurement, not a recommendation: we do not know why a tactic is missing, whether it belongs here, or whether adding it would change anything. Where a walk stopped early, a tactic living deeper would also read as not detected.

9 run · 3 flagged

contrast, mobile, typography, accessibility, weight — each with what would fix it

measured

Readability & contrast1 flagged

Text contrast (WCAG AA) needs workcontrast:text-contrast-wcag-aa

93% of measurable text passes WCAG AA. 4+ runs fail.

worst: “Token Context Window” at 2.53:1 (13px, #525252 on #0a0a0a). needs 4.5:1

fix Raise text/background contrast to ≥4.5:1 (≥3:1 for large text), especially on CTAs and body copy.

Mobile & tap targetsclear

Mobile viewport passesmobile:mobile-viewport

Responsive viewport meta is present.

Typography1 flagged

Body text size needs worktype:body-text-size

Smallest body text is 12px (base ~20px). below the ~16px readable floor.

fix Keep body copy ≥15-16px; reserve sub-13px for fine print only.

Line length notetype:line-length

4 paragraphs run past ~95 characters per line.

fix Cap measure at ~60-75ch for comfortable reading.

Accessibility hygieneclear

Weight & delivery1 flagged

Page weight not measurableweight:page-weight

At least 0.3 MB across 27 measurable resources, but 23 cross-origin resources did not expose a size. The true weight cannot be determined from the page.

Render-blocking resources noteweight:render-blocking-resources

5 stylesheets/scripts in <head> block first paint.

fix Defer non-critical JS (defer/async) and inline only critical CSS.

Oversized images needs workweight:oversized-images

11 images are shipped at more than 2x the width shown.

“submitaitools.png” is 600px wide, displayed at 54px

fix Serve responsive sizes (srcset/sizes) matching the rendered width.
