Measure it. Then say it.

Contrast, one pair

WCAG 2.x. Normal text needs 4.5:1, large text and controls 3.0:1. Translucent colours are composited over the ground, not guessed.

Estate audit, one folder

Choose a folder of HTML and CSS. It is read on your device. Nothing uploads.

Same math and thresholds as the instrument that audits this estate (contrast.py and contrast_audit.py); the folder audit is a browser subset: token contrast, links that resolve within the folder, visible copy per page against a 1400-character budget, placeholders (YOUR_, REPLACE_ME, lorem, localhost, TODO), and viewport, lang and canonical presence.

Material characteristics, one part

State what a part has to survive. The instrument proposes material families that meet it, a rough combination, and an estimated mass for the volume given.

Computed in your browser from published property ranges. It proposes families, never a formulation, because a formulation that fits a table is not the same as one that survives a mould. Treat the output as a shortlist for a materials engineer, not as a specification.
