Built and shipped the Superficies tracer-bullet app: Vite/TypeScript
single-file catalog with deterministic hash state, preset/live controls,
hero layouts, specimen strip, token diagnostics, export workspace,
GitHub Pages deployment, and responsive desktop/mobile editing
chrome.
Completed the original Beads epic and follow-up polish: long-hash
base64 fallback, font-pair constraints, safe escaping/validation,
dark-mode color cascade, scroll fix, Both mode, theme-aware panes,
TUI/CLI archetypes, terminal hero layout, export topbar CTA, and About
onboarding.
This session reviewed the latest CSS fixes for similar regressions,
fixed export-output theming, mobile Both-mode stacking, magazine action
overflow, and retitled the app to “Visual system workbench”.
Added export-modal polish: changing full-brief format preserves the
open modal, and one-click downloads now save the full brief
(.xml/.md) and token JSON (.json)
with deterministic filenames/MIME types.
Validation stayed green (npm run build; 44 tests after
download additions), and changes were committed/pushed to
origin/main as
116112d feat: add export downloads and polish preview layout.
Decisions: keep export downloads client-only via
Blob/object URLs; keep full-brief extension tied to XML/Markdown format;
keep token JSON as a separate direct-download action rather than
overloading the active export tab.
Arc: moved from research/spec setup through a
deployed tracer bullet and complete epic, then into
design-polish/productization: better archetypes, layout/theme
correctness, and practical handoff downloads.
Next: run browser smoke checks for the export
download buttons and recent layout fixes; if continuing feature work,
consider the previously noted color palette widget and start by running
wai search "color" /
wai search "palette".
