/* Society public-chamber composition.
   Shared across the public landing and the Letter of Inquiry (and any
   future world-facing surface — About the Council, Annual Bulletin).
   Internal/Fellows-only surfaces have their own component sheets
   (common-room.css, wire.css, stacks.css, cable-form.css).

   Source: extracted from society-landing.njk Phase 1 exploration after
   promotion to Phase 2 iteration (society-public hub). The Phase 1
   exploration is the receipt of the responsive composition question
   answered by this code.

   Token usage: every color reads from --soc-* so the navy flavor flips
   the whole surface without per-selector overrides. */

   Letter treatment — `.is-letter` modifier.

   Apply `.is-letter` to any container that should read as a letter
   from a Society officer rather than plain body copy: justified with
   hyphens, a hairline gilt rule beside any heading, a gilt drop
   initial on the first paragraph, and (if a `.hero-signoff` line is
   present) a right-aligned signature.

   Surfaces:
     · `.hero-copy.is-letter` — Landing hero (Master), Bulletin

       (Master). The hero-context adds inset padding so the letter
       reads pulled-in from the page edge.
     · `.loi-form-letter.is-letter` — the brief Honorary Secretary's
       note that opens the Letter of Inquiry, before the form proper.
