docs(design): composition and the reader — a chapter and a Conformance step (E30 S6)

The rules covered each piece; nothing asked whether a screen works as a whole, and the person page passed
every rule with half its panel empty. New chapter: the space is used, one focal point, worst real data,
where am I, a click answers at once (no outside service on open), zoom and text size first-class (the
owner reads zoomed in). Conformance step 5 writes one composition line per screenshot and checks 200%
zoom and the largest text size. Anti-patterns and a decision-log row to match.

HU: the download worker setting reads "Párhuzamos letöltések" (a leftover from the S5 sweep).

+The rules above say how each piece looks; these say whether the screen works as a whole, for the one
+reader it is built for. Found when the person page passed every rule with its biography in the left half
+of a full-width panel and nothing on the right.
+
+- **The space is used.** A narrow element in a wide container (prose at `measure`, a form, a short list)
+  comes with a decision about the rest of the width: a second column with related content (the person
+  page: facts and bio left, "Known for" right), a container sized to its content, or a layout that stacks.
+  A band of nothing wider than about a third of a panel, beside content that stops short, is a finding.
+  [Material layout, Gestalt proximity]
+- **One focal point, then an order.** A screen has one thing the eye lands on first (the page heading, the
+  hero, the player), then the sections, then the metadata. A heading level keeps one look across screens;
+  a second focal point competing with the first is a finding. [Nielsen #8, HIG hierarchy]
+- **Worst real data, not the demo row.** A screen is judged with the longest title, the Hungarian label,
+  zero items, the largest list, a missing picture and a missing field. None of them clips, overlaps or
+  leaves a hole where a value was. [Nielsen #9, WCAG 1.4.10]
+- **Where am I.** The browser tab names the place and the object in it ("Nicolas Cage · Plex · Siftlode"),
+  the rail marks the place, and Back returns to the same view at the same scroll position with focus
+  where it was. [Nielsen #1, WCAG 2.4.2]
+- **A click answers at once.** A control shows its pressed or changed state within ~100ms (an optimistic
+  update, a spinner in the control); what a screen opens with is the app's own data — an outside service
+  (TMDB, YouTube) is fetched ahead of time by a job, not on the click, so a page never waits on it.
+  Late content keeps its place (B8). [Nielsen #1, RAIL]
+- **Zoom and text size are first-class.** The owner reads with the browser zoomed and a large text size.
+  Every screen holds at 200% browser zoom on a desktop window and at the largest Settings text size at
+  1024 wide: nothing clipped or overlapping, no sideways page scroll, every control reachable and at
+  least its rung, text wrapping rather than cut. Measured, not assumed, on every UI change. [WCAG 1.4.4,
