Source-bound surface survival

Rendered evidence
The graphic shows re-theme survival: the register changes, but the component grammar holds.

HERMES case-study frame

Read the case before the evidence room.

A reviewer should be able to answer seven things before opening the JSON export: what decision is in front of them, what changed against a cold start, which row carries the claim, where the value appears, what source trail exists, what purchase decision it informs, and what the case does not prove.

  1. 01 · Buyer question

    What is being decided?

    A design lead wants to see whether source-backed surfaces can change register without becoming a pile of one-off styles.

  2. 02 · Cold start

    Hand-themed surface

    A page changes mood by introducing new color values, new spacing, and special-case component CSS.

  3. 03 · KBPD-backed

    Source-bound surface

    The same component contract reads a different brand-source cluster. Structure holds while register changes.

  4. 04 · Boundary

    Demonstrator

    This proves visual system survival, not buyer conversion.

Claim

A single brand-source system can render different surface moods while preserving component structure, spacing rhythm, and motion rules.

The visible proof is re-theme survival: the page changes mood without losing the underlying component grammar.

Before / after

Same use case. Different starting conditions.

Before · visual one-off

Hand-themed surface

A page changes mood by introducing new color values, new spacing, and special-case component CSS.

The look changes, but every variation becomes another thing to maintain.

After · design-system specimen

Source-bound surface

The same component contract reads a different brand-source cluster. Structure holds while register changes.

Palette, type, spacing, radius, and motion stay bound to the same named system.
