Per mara's review question on PR#3219 ('shouldnt the jsx files import
their css?'): each component now does its own import ('./Shell.css',
'./Panel.css', ...) instead of swarm-ui.css centrally @import-ing
every component's stylesheet. esbuild folds every .css reachable from
main.tsx's import graph into one main.css companion output next to
main.js — no separate build step, this is bundle:true's existing
behavior, just not exercised until now.
swarm-ui.css keeps only the shared base reset (@hive/shared/base.css)
since that isn't any one component's concern. Added src/css.d.ts
(ambient '*.css' module) since tsc otherwise rejects a side-effect
import of a non-JS/TS specifier.
Side benefit: a component nothing imports (yet) no longer ships its
CSS either — StatusChip/Table aren't referenced from App.tsx today,
and main.css correctly only carries Shell.css + Panel.css. The old
central-import approach shipped all four unconditionally.
npm run build + typecheck clean. Re-screenshotted the real dist —
pixel-identical to before this change.
