Introduces a dedicated documentation site at /docs/, built as a second Vite
entry point alongside the app and deployed to the same GitHub Pages site. It
documents every feature — the matrix, team, tasks, schedule, and insights tabs,
the goal bar and global controls, theming, CSV/JSON import, and the Talk2View
assistant — plus a from-the-code walkthrough of the two algorithms (quadrant
weights, capacity budget, and burnout thresholds for assignment; slot scoring
and energy/concentration matching for scheduling). A philosophy section records
where the method came from: the Eisenhower matrix the team kept drawing on paper
and whiteboards while running internal projects at Talk2View Pty Ltd, and the
annotations about who would enjoy, be good at, and have room for each task that
grew into the pleasure/talent/capacity model.

Every screenshot on the page is generated by Playwright rather than captured by
hand. A spec under tests/e2e/screenshots reuses the existing e2e fixtures and
seeds to drive the live app — seeding the demo project, freezing the clock so
the schedule sub-views fill with real blocks, and loading the real fonts — then
writes thirteen PNGs into public/screenshots/. The deploy workflow regenerates
them before `vite build` (which copies them into dist/screenshots/), so the
documentation never drifts out of date with the deployed UI. The capture step
is best-effort: a transient failure degrades the docs to graceful placeholders
rather than blocking the site deploy. The screenshots are gitignored and can be
regenerated locally with `npm run screenshots`; the spec lives outside the e2e
testDir and uses its own config, so `npm run test:e2e` never runs it.

To let the docs reuse the app's exact look without bundling the whole
application, the theme machinery, colour and style objects, and the small
Pill/Slider/SectionHead primitives move out of App.jsx into a shared
src/ui/theme.jsx that both entries import. The documentation page wraps that
module in the real ThemeProvider, so theme presets, dark mode, and font choices
carry across and persist via the same storage key.

Finally, every primary control in the app — the five tabs, the header buttons,
the add-member/task/category/stakeholder actions, and the schedule view switcher
— gains a tooltip (src/ui/Tooltip.jsx) that pairs a one-line description with a
"Learn more" link deep into the matching /docs/ section, and the header and
footer gain a direct link to the documentation.
