Resolves the two conflicts in components/calendar/event-modal.tsx created
by #967 (RSVP controls), both keep-both:
- #967's canRsvp memo and #986's resolveContactName hook are both kept;
they are independent and were simply inserted at the same point.
- #967's RsvpBar component is kept, and StatusBadge takes #986's
signature ({ status, t }) since #986 drops the isOrganizer prop and
updates both call sites to match.
Some senders ship the images their HTML body embeds via cid: as
application/octet-stream with no Content-Disposition and no filename.
The body rendered them fine, but the "hide inline images" check only
recognised parts declared inline with an image/* type, so they also
showed up as nameless "Attachment" chips next to the real files.
Both viewers now scan the HTML they actually render for cid: references
(the same pattern the renderer rewrites to blob URLs) and hide a
referenced part when it is an image or generically typed. An explicit
attachment disposition always keeps its chip, as does a referenced part
with a real non-image type, since that chip is its only download. Plain
text rendering references nothing, so nothing is hidden there. The
shared rule lives in lib/attachment-visibility.ts so the desktop viewer,
the thread view and the decrypted-message path cannot drift apart.
isHttp2Available() only inspected "resource" timing entries, which can be
empty right after a fresh login or session restore, before any subresource
finishes loading. On an HTTP/2 page this made getMaxAccounts() fall back to
the HTTP/1.1 cap of five accounts. Include the "navigation" timing entry,
whose nextHopProtocol is known immediately, so h2/h3 is recognized on first
load. Environments without timing data still return false (no h2 assumed).
The browser paints a native <select>'s option list itself, so the
bg-muted / text-foreground classes on the control never reach it. Themes
whose --color-muted is translucent (Aurora Glass dark uses
rgba(255,255,255,0.05)) composited to a light popup with near-white
text, leaving every unselected option almost invisible.
Pin option background/colour to the popover tokens, which every built-in
theme defines as an opaque surface, and set color-scheme: dark on
selects under .dark so Safari (which ignores option colours) renders a
dark popup too. Fixes all ~40 native selects at once.
Adds a stylesheet test that locks the rules and asserts every built-in
theme's --color-popover stays opaque in each variant.
