The shallow <hash> frames can not advertise capabilities.

Here's what goes over the wire:

To reproduce this, you can:

To reproduce the first issue, do this:

Ignore this, test.

D20573 will fix this, but perhaps not in the most graceful way possible.

I applied this change to 20180208.maniphest.02.populate.php:

See also PHI1275. Now that Phriction supports relative references in [[ ... ]] syntax, moves should be able to modify those references.

New before:

• Remove "h1" rule, which is never used (the largest header is "<h2>", with the page header being "<h1>").
• Adjust sizes a bit more.
• Remove redundant weird override in some other file.
• Simplify margins slightly.

This also means that the actual page header (for example, the document title on a Phriction page) may be smaller than an <h1> in the same document.

• Add a couple of extra non-semantic newlines to the test cases for prettiness.

• More wordsmithing.

Oh, I edited "an to edit" into "an rule to edit" or something. Perhaps not my greatest work.

• Wordsmithing.

I'm just going to close this in the hope it fades quietly into the night now that it has been "fixed".

D20563 probably fixes mail. I don't think (?) it will fix notifications but haven't hunted that down yet.

• Share more API in Differential.
• Add support in Diffusion for good measure.
