Mobile themes · readable contrast and image provenance

The second pass strengthens muted text, date/link text and keyboard focus, including the dark sidebar in light mode. Native controls share each theme. Contrast pass: dark phone overview: 20261014T205909220000-1daff20c9838, [image retained in local archive] (site screenshot; 2026-10-14T20:59:09.220Z; overview-ui-f56ddd996e42-1e1f4b48f187). Provenance: readable source details in the 320px dialog: 20261014T205909574000-6542ab2ff0bd, [image retained in local archive] (site screenshot; 2026-10-14T20:59:09.574Z; overview-ui-f56ddd996e42-1e1f4b48f187). Measurement snapshot on 14 October 2026, UI overview-ui-f56ddd996e42-1e1f4b48f187: muted text against the light hero improved from 4.12:1 to 4.71:1; the sidebar focus ring improved from 2.68:1 to 7.89:1; the narrow dialog measured 298px client width and 298px scroll width, with a 44px close button. Source: CSS color calculations and rendered browser DOM; Escape closed the dialog. These selected contrast pairs do not certify the entire site. An archive panel still needed a narrow-width stacking refinement.
