refactor: delete unreferenced components and the unused hiIQ ABI

[invisiblemask]

Stacked on #76, which is stacked on #74. Review those first.

Pure deletion — 17 files, 1,942 lines, two dependencies. No behaviour changes.

How dead was verified

For each candidate: no import of the file by path anywhere in src, i18n, messages or the root configs, and no reference to any exported identifier. Then pnpm build with a full TypeScript pass, which is the authoritative check for a broken import.

This turned up more than the four files I flagged during #74. Two were mislabelled as live by a first pass and had to be re-checked by hand — zod-enum-from-record is used by messages/_schema.ts, and ui/button / ui/dropdown-menu are used by locale-switcher. Both stay.

What goes

File	Why
src/abis/hiIQABI.abi.ts (786 lines)	getLockOverview calls Alchemy with a hardcoded 0x18160ddd totalSupply() selector and never loads an ABI. Dead since it landed.
icons/1inch.tsx	Duplicate of one-inch.tsx, exporting the same OneInchIcon name. data/exchanges.ts imports the latter.
icons/{QuickSwapIcon,bitget,bithumb,cryptocom,fraxswap,iq-wiki,sushiswap}	Venues the current design dropped — markets now shows Binance, Upbit, 1inch and Frax.
svgs/ (all 4)	BraindaoLogo, BraindaoLogoDark, BrainLogoWhite, HeroBackground — superseded by layouts/brand-logo and layouts/hero-orbits. Directory removed.
transitions/InViewAnimateBottom.tsx	Unused and broken. Directory removed.
ui/{card,container-scroll-animation,popover}.tsx	Unused shadcn scaffolding.

InViewAnimateBottom is worth calling out: it destructured const { inView } = useInView() without ever attaching the observer's ref to a node, so inView was permanently false, and the useAnimation() controls it drove were never bound to any motion component. The animation that actually ran came from whileInView on the motion.div. So the component was doing nothing even if something had imported it.

Dependencies dropped

• @radix-ui/react-popover — sole consumer was ui/popover.tsx
• react-intersection-observer — sole consumer was InViewAnimateBottom.tsx

Verification

• pnpm build clean; TypeScript pass clean; both routes generated
• pnpm biome check . clean (scope drops 89 → 72 files)
• Dev server, /en and /en/hiiq: 29 SVGs, 0 empty, 1 zero-box (the hidden mobile hamburger) — identical to the pre-deletion baseline
• All 7 chain and venue icons in #markets render with real geometry and child nodes, including 1inch at 18×18 from the surviving one-inch.tsx
• Footer socials render (3 SVGs); #treasury anchor resolves; live data intact (0.0006 / 16.68M / 27B / 2.5B locked, and 8B HiIQ on /hiiq)
• Console clean apart from HMR websocket noise from the server restart

Note on the stack

Ten of the files reformatted in #76 are deleted here, so most of that PR's churn evaporates at merge. Leaving the order as-is rather than rewriting two open PRs' history — but if you'd rather review a small #76, say so and I'll reorder the stack so the deletion lands first.

One non-deletion change

pnpm remove silently dropped the pnpm.comment key documenting why the overrides block exists and that Tailwind 4 retires it — pnpm rewrites its own pnpm field and discards keys it doesn't recognise. Restored as a top-level "//pnpm", which survives an add + remove round-trip (verified).

Rebased on the updated base

The merge of #73's hiIQ page rewrite is propagated down the stack (#74 → #76 → here). No conflicts at this level. Re-verified after the merge: none of the 18 files the base added imports anything this PR deletes, biome check . is clean over 84 files, pnpm build and the TypeScript pass are clean, and all three deleted directories stay gone.
