Five products, five specs

Build a waitlist landing page.

Above the fold: a single sentence of positioning, an email field, and
nothing else. Below: three proof blocks and an FAQ.
On signup: store the email, assign a referral code, show queue position,
and generate a share card.
Admin: signups over time, referral leaderboard, CSV export.
Daily digest email to the owner at 9am with yesterday's numbers.
Design: one accent colour, editorial type, zero stock illustration.

Build a client portal for a design studio.

Roles: studio admin and client, in a separate role table.
Client sees only their own projects: milestones with status, delivered
files, and an approve/request-changes action with a comment.
Admin sees all projects, uploads deliverables, and moves milestones.
Email the client when a deliverable lands and the studio when a
decision is made.
Design: quiet, document-like, generous white space, no dashboard chrome.

Build an internal ops dashboard.

Top: four number tiles with week-over-week deltas.
Main: one dense sortable table with column filters and saved views
per user.
Alerts: set a threshold on any metric and email when crossed.
Access: staff only, role-checked server-side.
Design: information-dense, small type, no cards-in-cards, monospace
for numbers.
