Two notes on the source material.
1 · The funnel runs entirely on Barlow. Barlow and Barlow Condensed come from Google Fonts, and every layer above — headings, answers, sub-heads and body copy — resolves to one of the two. The guidelines name Avenir as the body face on p.24, and several Figma frames still carry Arial or Avenir on the sidebar and chrome, but those are the un-restyled legacy layers rather than a call against the brand (Nam, 2026-07-30). Avenir stays defined and self-hosted from this prototype’s own assets/fonts/ — Light / Roman / Heavy, unused at present — so pointing body copy back at it is a one-line change. Note that copy is the one bundled with macOS: right for a gated prototype, but not a web licence, so anything public would need Audibel’s licensed webfont.
2 · The guidelines mislabel one swatch. On p.32 the “Passion” secondary tone is printed as #A96B27 — the same hex as the “Energy” tone — while its stated RGB (129 / 72 / 64, PANTONE 499 C) is #814840. Grace’s call: use #814840, applied above.

Read before using this.
1 · These are not the real faces. Mr Eaves XL San OT / Mod OT (Emigre) and DIN OT are licensed and are not installed on this machine, so the preview uses the closest free stand-ins — Mulish for Mr Eaves and Archivo for DIN. The weight and proportion read true; the letterforms do not. Send the real files the way you sent Avenir and they go straight in.
2 · The guide names no web fonts. p.19 says the same headline and body rules apply on the web “however specific fonts need to be used in order to keep compliant with the font licenses we own” — without saying which. Worth asking Starkey what the licensed web faces are.
3 · No type scale. The guide gives faces and roles but no sizes, so the preview keeps the funnel’s existing sizes and changes only face, weight and colour.
