Upgrades that compound.

Fixed-fee work for sites that are ready to do more — a move onto native classes, a migration, or real engineering layered onto what you already have. Pick a package, the scope is written down, and the work ships on a clock.

Six packages, every price on the table.

Each one assumes a site to build on. If you are starting from nothing, a standard build is the right way in, and we will say so rather than stack upgrades on an empty page.

The first, dark mode done right, is shown here in Terminal: every colour on the page is a variable with a Light and a Dark value, so switching the theme swaps values and leaves the markup alone.

Send a brief for dark mode
Terminal's variables at work on a client page, Lumen Dental. A short demo plays: the canvas mode menu switches the page from Light to Dark, the Forest and Ink themes re-colour it, Light and the Ember theme come back, and a new mode called High contrast is added, its values following Light until they are set. The controls beside the drawing are real: pick a theme, show a mode on the canvas, or add a mode.

A platform, not a site

A marketing site and a full-stack application deployed together — staging and production environments, multi-tenant data where it applies, admin tooling, and a dedicated retainer after launch. Quoted per project.
