bridge_fit: Maker label "High Bridge Fit" mapped using Oakley's published definition (src_oakleysi_oo9250_0357).

Notes: Two WebFetch extractions of this URL with differently worded prompts; only values both returned identically are recorded. Size label is Oakley's tech-spec 'Size' value; the page gives no lens width, nose bridge, temple length, lens height, overall frame width, UPC or EAN, so those are omitted (the mm figure in the size label is not labelled as a specific dimension). Tech-spec 'Fit' row read 'Regular'. Lens category disagreed (A: not present, B: 'Bright Light', which is the Light Conditions value) and was omitted. Size follow-up (2026-09-25T08:33:27Z): lens/bridge/temple(arm)/lens height/frame width from Oakley's own Standard Issue site (oakleysi.com), two agreeing WebFetch extractions; that page served OO9448-0157 with size M (133mm), matching this variant's oakley.com size label. The oakleysi.com page did not serve this colour (OO9448-0657); values are the style's measurements for the same style code and size (single-size style), not colour-specific. SportRx (retailer) prints different, self-measured figures for some styles (e.g. Holbrook: Lens Width 57mm / Bridge 17mm / Temple 128mm / Frame Width 132mm); not recorded.
