Before: the on-sky lockup had a dark mark with dark cutouts — the fold
V-shape disappeared because the cutouts matched the mark colour instead
of the sky backdrop. Same on cream.
Now three per-surface mark variants, cutouts coloured to match the
expected background so it shows through:
mark.svg sky body + navy cutouts → dark panel
mark-on-sky.svg navy body + sky cutouts → sky-blue surface
mark-on-light.svg navy body + cream cutouts → light surface
Logo lockups rebuilt the same way: logo-horizontal-on-sky.svg uses the
dark+sky mark variant, logo-horizontal-light.svg uses the dark+cream
mark variant, same for stacked.
Branding page's on-sky / on-light preview cells repointed at the new
variants. addon.json bumped to 0.2.6 (same mark, re-emitted from
pipeline for byte parity with the sites).
Follow-up to 120dd8e1 which committed only the branding page rewrite but
dropped the binary assets. All kit files now land in both mirrors:
site/hermes/branding/ and site-hermes-x/assets/.
Each generated by the Python compositor at
scratchpad/build_brand_kit.py from the user's own file.svg master.
