The single 576-line global sheet grew with every card (trend chart,
browser, file activity, agent graph...), so every component change
opened the same shared file. Cut it mechanically into 14 cohesive
sheets under src/client/styles/ — one per component surface plus a
base sheet (root/card chrome, the lc-gran toggle, list anatomy,
error states, the composer-hiding rule).
Rules are byte-identical to the previous single sheet; index.ts
imports them in the original section order so the cascade is
unchanged (base first — later sheets re-tint the shared gran chrome
at equal specificity). bundle-smoke.mjs now asserts one style tag
per sheet instead of the single dsh-context/styles.css tag.
