docs: draft ten logo concepts

Eight fresh directions plus two refinements of the shipped mark, each authored as a real currentColor SVG in the app's house style rather than as a description, so any of them can be dropped straight in and the favicon tile is a mechanical derivation. Every mark was rendered at 120/32/24/16px and looked at, which changed the set three times: the braid came out as a plain multiplication sign and was rebuilt with actual over/under crossings, the anchor was rebalanced to three-fold symmetry, and the first return-arc read even more like a copyright glyph than the current one. The finding that matters is not one of the eight. The mark shipping today fails at 16px — its outer strokes drop out to rasterisation and the 2.5px gap to the node fills in, so the favicon renders as a smear. Concept 09 fixes that in five lines and is worth taking regardless of whether anything here replaces the mark. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
