landing: re-verify every client claim (reviewed 2026-09-26)

Each client's card and all 64 table cells were checked against its latest
release (source at the release tag, changelogs, official docs):
Cinny v4.12.7, Element Web v1.12.29, Element X 26.09.2, FluffyChat
v2.9.5, Commet v0.5.0, Nheko v0.12.1. ~95 cells corrected, notes
tightened, chips made consistent (platforms / SDK / one calling chip).

Notable:
- Cinny: calls, voice rooms and screenshare via Element Call are stable
  (card gained the calling chip); ring, who-reacted, read receipts: yes;
  polls: no.
- Element X: cannot START a screenshare (mobile web views have no
  getDisplayMedia) — chip is now "Voice & Video".
- FluffyChat: threads, pinning, media gallery, custom status, QR invites:
  yes; calls still experimental (DM-only, legacy 1:1).
- Commet: web app + Windows/Linux, no macOS; screenshare, widgets
  (v0.5.0), favourites: yes; "Beta" chip dropped (not self-described).
- Nheko: calls are 1:1 only and only in Linux builds; threads: yes; no
  release since Aug 2025.
- Element: no bookmarks or scheduling; custom status is Labs; QR invites
  and sort order: yes.
- Lotus Chat: Vodozemac yes (Rust crypto), widgets yes, push = only while
  open (no background push yet); desktop app is Windows + Linux (the
  feature list said macOS).
- Vodozemac is yes for every js-sdk client now (Rust crypto).
