How this was measured
Measured by Roentgen 1.27.0 on 2026-09-11. 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 7 that apply to a content funnel.
Walk 281 links on the entry page, 273 walkable. 1 matched a funnel step; we captured 2 pages in all, this one included.

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.

Tap-target size (mobile)
mobile:127 of 161 interactive targets are under 44×44px on mobile.

FixGive tappable controls a ≥44×44px hit area. the touch minimum.
Named controls
a11y:16 buttons/links have no accessible name (icon-only, no aria-label).
FixAdd aria-label to icon-only buttons and links.

FixServe responsive sizes (srcset/sizes) matching the rendered width.
Worth knowing7
Image alt text
1 of 19 content images (5%) have no alt attribute.
FixAdd descriptive alt to content images; alt="" for purely decorative ones.
a11y:Form labels
1 form field relies on placeholder text as the only label.
FixBack placeholders with a real <label>. placeholder text vanishes on input.
a11y:Heading levels
3 headings skip a level (e.g. <h2> followed by <h4>). Screen-reader users navigate by this outline.
FixStep heading levels one at a time; use CSS for size, not a deeper level.
a11y:Skip link
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:Landmark regions
No <main> landmark. screen-reader users cannot jump between regions.
FixWrap the page in <header>, <main> and <footer> (or matching ARIA roles).
structure:Keyboard reachability
6 elements look clickable but cannot be reached by keyboard.
FixUse <button>/<a>, or add role + tabindex="0" and a key handler.
structure:Autocomplete hints
No autocomplete attributes across 3 fields. browsers cannot autofill.
FixAdd autocomplete="email"/"tel"/"name" to identity fields.

We ran these passes on the pages we captured and found nothing to show. That is a measurement of this funnel, not a recommendation — and it is a different statement from a layer we never ran, which does not appear here at all.
