Adds /png-to-jpg, /webp-to-png, /jpg-to-png, /compress-image — each an INTENT_PAGES row opening CapyResize on a preset (D21 amended, D48).

Page	Opens with	Google / mo	Bing / 12 wk
/png-to-jpg	initialFormat="jpeg"	1M–10M	166,421
/webp-to-png	initialFormat="png"	100K–1M	115,317
/jpg-to-png	initialFormat="png"	100K–1M	103,129
/compress-image	initialFormat="jpeg", initialQuality={0.7}	100K–1M	82,678

• CapyResize: new initialQuality prop (default 0.85, unchanged) replaces the hard-coded useState(0.85).
• /compress-image uses JPEG, not WebP: every browser writes JPEG; a browser that can't encode WebP silently returns PNG — the opposite of compressing. The copy names WebP as the one-click alternative and explains the fallback.
• Claims checked against code: JPEG fill is the "Flatten onto" picker, default white (not sampled); before = dropped file size, after = encoded blob size; PNG has no quality slider.
• CONTENT_UPDATED was already 2026-10-09 — nothing to bump.
• scripts/smoke.mjs PAGES updated; decisions.md D48, learning.md L37.

Verified

• vitest 92 files / 2024 tests pass; npm run lint 0 errors; next typegen && tsc --noEmit clean.
• Dev server: each page's <title>, canonical and guide (+ FAQPage JSON-LD) are in the server HTML; correct format pre-selected.
• Real conversions in the browser: PNG(alpha)→JPG gave image/jpeg, transparent corner = white, 111 kB → 41 kB; WebP(alpha)→PNG gave image/png, corner alpha 0 kept, 35 kB → 330 kB (larger); JPG→PNG gave image/png, 57 kB → 555 kB (881% larger); compress-image opened at quality 0.70, JPG 105 kB → 27 kB (74% smaller).
• Not exercised: the WebP→PNG fallback (Chrome encodes WebP) — code-read only.
