Measured by Roentgen 1.25.1 on 2026-08-17. A capture is read once and its measurements freeze there, so the stamp says which ruleset read this one.
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. Per device: desktop 70 · mobile 70.

applicable tactics we checked for and did not see on any step we reached
measuredextracted directly from the live page. a fact, not an opinionAbsence 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.
contrast, mobile, typography, accessibility, weight — each with what would fix it

84% of measurable text passes WCAG AA. 4+ runs fail. 18% of text was unmeasurable (over images/gradients). not counted either way.
worst: “SupaSidebar” at 1.02:1 (20px, #fffdf5 on #ffffff). needs 3:1
FixRaise text/background contrast to ≥4.5:1 (≥3:1 for large text), especially on CTAs and body copy.
Smallest body text is 10px (base ~14px). below the ~16px readable floor.
FixKeep body copy ≥15-16px; reserve sub-13px for fine print only.
15 stylesheets/scripts in <head> block first paint.
FixDefer non-critical JS (defer/async) and inline only critical CSS.
13 images are shipped at more than 2x the width shown.
“leblogducuk.png” is 1158px wide, displayed at 42px
FixServe responsive sizes (srcset/sizes) matching the rendered width.
No <main> or <header> landmark. screen-reader users cannot jump between regions.
FixWrap the page in <header>, <main> and <footer> (or matching ARIA roles).
123 of 179 interactive targets are under 44×44px on mobile.
smallest: “Home” at 34×15px
FixGive tappable controls a ≥44×44px hit area. the touch minimum.
3 paragraphs run past ~95 characters per line.
FixCap measure at ~60-75ch for comfortable reading.
type:2 form fields rely on placeholder text as the only label.
FixBack placeholders with a real <label>. placeholder text vanishes on input.
a11y:No same-page “skip to content” link was found. Keyboard users tab through the whole nav on every page.
FixAdd a first-in-DOM <a href="#main"> that is visible on focus.
a11y:38 controls have an aria-label that does not contain its visible text, so voice-control users cannot activate it by saying what they see.
FixMake the accessible name start with the visible label text.
a11y:No autocomplete attributes across 2 fields. browsers cannot autofill.
FixAdd autocomplete="email"/"tel"/"name" to identity fields.
forms:At least 0.7 MB across 270 measurable resources, but 81 cross-origin resources did not expose a size. The true weight cannot be determined from the page.

Arc Browser vs SupaSidebar
A match means this funnel's measurable surfaces fit the playbook's pattern — the quoted language is what fired the detection. A lever is one playbook mechanism observed on-page. We never claim what a brand's ads or emails do; a crawl can't see them. All funnel designs →
Two different things sit side by side here. The claim and its quoted evidence are measured on this funnel, the same way every other fact on this page is. The playbook itself is written guidance — our strategy library, not a measurement of this site — and it lives behind the links above. Nothing on this page recommends what this brand should do.
