Mirror the S5a web dual-display in the WeasyPrint PDF cover: equal-prominence
«Ожидаемая цена продажи» figure (value + range + ₽/м²) next to «Ориентир
запроса», with a −N% discount chip and the ДКП-Росреестра explainer. Graceful
single-asking fallback when expected_sold is None/0; each sold sub-field guarded.
Pure rendering change — no DB/schema/API impact. WeasyPrint import made lazy so
the HTML builders are testable without the native GTK stack.

Show «Ориентир запроса» (asking median) and «Ожидаемая цена продажи»
(expected sold, S3 rosreestr ДКП) as two EQUAL-weight figures (same value
typography; sold card gets a subtle accent tint only), each with range +
₽/м², plus a tasteful −N% discount chip (aria-labelled, Unicode minus) and
an explainer. Graceful: expected_sold null/0 (old estimates / empty ratio
table) → single asking figure, no empty card/rows. Tokens-only CSS, responsive.
tsc --noEmit clean (TS strict); npm run build passes.
